Lessor operates the antenna sites (the "Site(s)") described in the Antenna Site
Lease Schedules executed and delivered by Lessor and Lessee pursuant to this
lease (the "Lease") from time to time (each in substantially the form of the
attached Exhibit C, and a "Site Schedule" and, collectively, the "Site
Schedules", each of which, when and as executed, are and shall be incorporated
herein by this reference. Lessor desires to lease to Lessee and Lessee desires
to lease from Lessor certain space at the Sites for installation and operation
of Lessee's equipment on the terms set forth in the Site Schedules and herein.
If the terms of a Site Schedule conflict with this Lease, the terms of the Site
Schedule shall control, but only with respect to the Site(s) that are the
subject of such Site Schedule and the Site Information (defined below). Now,
therefore, the parties agree as follows:

     1.   LEASED PREMISES:

          (a)  Lessor leases to Lessee and Lessee leases from Lessor certain
               space at the Sites as specified and described in the Site
               Schedules (individually and collectively the "Leased Premises").
               Lessee agrees to take the Leased Premises in strictly "AS IS"
               condition, and acknowledges that Lessor shall have no
               responsibility for the condition of the Leased Premises or any
               damage suffered by Lessee or any other person due to such
               condition. If a Site Schedule provides that Lessee's equipment
               will be connected to a Lessor-provided antenna system, Lessee
               shall be responsible for all costs of accessing Lessor's antenna
               system including but not limited to the costs of combiner modules
               and other equipment required for the connection.

          (b)  Lessee shall pay Rent (defined below) as specified in Section 3
               and shall endeavor to use the following aggregate minimum number
               of Sites during each month of each year of the term hereof as
               indicated (the "Site Commitment"): (i) *** Sites during each
               month of the first year of the term hereof; (ii) *** Sites during
               each month of the second year of the term hereof; and (iii) ***
               Sites during each month of the third year of the term hereof. For
               purposes of calculating the total number of Sites leased by
               Lessee and for determining whether Lessee has met the Site
               Commitment, one (1) One-Way Site (defined below) shall equal one
               (1) Site, and one (1) Two-Way Site (defined below) shall equal
               two (2) Sites, which yearly amounts shall be reduced by the
               aggregate number of Sites that become "Removed Sites" (defined in
               Section 24) following the Effective Date. Lessee shall have no
               requirement to maintain any minimum number of One-Way Sites or
               Two-Way Sites. The Rent specified in Section 3 hereof as adjusted
               for Removed Sites shall be due and payable by Lessee to Lessor
               regardless of whether Lessee meets the applicable Site
               Commitment. The failure of Lessee to meet the Site Commitment
               shall not result in a breach by Lessee of this Lease or affect
               Lessee's obligation to pay the Base Rent, the Monthly Reservation
               Fee or any Acquired Site Rent (defined below).

          (c)  Lessee will have the right, at its sole cost, to relocate its
               equipment from one Site under this Lease to another site in
               Lessor's network not already subject to this Lease, subject to
               Availability (defined below) (a "Relocated Site"). Lessee shall
               provide Lessor at least five (5) business days prior written
               notice of Lessee's intent to relocate its equipment, or such
               notice period as is required under all affected Prime Agreements
               (defined below)

                                       2

               plus three (3) business days (provided that Lessor has provided
               Lessee with the relevant provisions of the underlying Prime
               Agreements). Lessor shall notify Lessee within ten (10) days
               after Lessor acknowledges receipt of Lessee's notice of proposed
               relocation as to whether the proposed Relocated Site is
               Available; failure of Lessor to respond within such ten (10) day
               period shall be deemed to be a determination that the proposed
               Relocated Site is not Available, and in such case the proposed
               site shall not be a Relocated Site. For the purpose of
               determining whether Lessee has met the Site Commitment, the Site
               from which Lessee relocated will not constitute a Site hereunder,
               and the Relocated Site to which Lessee relocated will constitute
               a Site hereunder but in any event no Acquired Site (defined
               below) will constitute a Site hereunder. Upon the effective date
               of any relocation under this Section 1(c), the parties shall
               terminate the then existing Site Schedule for the terminated
               Site, and enter into a new Site Schedule for the Relocated Site,
               which new Site Schedule shall be incorporated into this Lease.

          (d)  Lessor shall be entitled to remove any Site from its network for
               any reason in its sole discretion. In such event, then Lessee
               shall have the right to relocate to a Replacement Site, subject
               to Availability. Each Replacement Site shall be subject to a new
               Site Schedule, and each such Site Schedule shall be incorporated
               into this Lease. Lessor shall notify Lessee of Lessor's proposed
               removal of a Site under the first sentence of this Section 1(d),
               and of any Lessor sites which Lessor believes would be acceptable
               to Lessee as a Replacement Site hereunder, at least sixty (60)
               days prior to removal, unless a shorter period of time is
               required by the applicable Prime Agreement or other reasonable
               circumstance, in which event Lessor shall notify Lessee of the
               proposed removal, and of proposed Replacement Sites, promptly
               after learning of the facts which necessitate the removal. If
               Lessee accepts a proposed Replacement Site, such Replacement Site
               shall constitute a Site hereunder for all purposes, including for
               determining whether Lessee has met the Site Commitment and paid
               the amount of Rent owed hereunder. If no Replacement Site is
               accepted by Lessee within fifteen (15) days (as may be extended
               by mutual agreement of the parties) after removal of a Site by
               Lessor under this Section 1(d), such Site shall be deemed a
               "Removed Site".

          (e)  Lessee will have the right to add Sites ("Additional Sites") to
               which Lessor has title or other right to possession, subject to
               Availability. Lessee shall provide Lessor at least five (5)
               business days prior written notice of Lessee's intent to add a
               Site, or such notice as is required by Lessor's underlying Prime
               Agreement plus three (3) business days (provided that Lessor has
               provided Lessee the relevant provisions of the underlying Prime
               Agreement.) Each such Additional Site shall be subject to a new
               Site Schedule, and each such Site Schedule shall be incorporated
               into this Lease. Any such Additional Site shall constitute a Site
               for the purpose of determining whether Lessee has met the Site
               Commitment, and if as a result of such calculation Lessee exceeds
               its Site Commitment, then the Rent for each such Additional Sites
               shall for each month during which the Site Commitment is
               exceeded, be at the Arch Rate set forth in Section 3(b), in
               addition to the other Rent. Notwithstanding the foregoing, no
               Acquired Site may be added as, or otherwise constitute an
               Additional Site hereunder.

          (f)  In connection with Lessee's permitted relocation from a
               non-Lessor site to a Lessor Site under this Lease, Lessor will
               provide to Lessee a relocation allowance (the "Relocation
               Allowance") for the subject new Site equal to the sum of (i) ***
               of Lessee's cost incurred and paid to third parties to relocate
               its equipment to such new Site from a non-Lessor site (not to
               exceed, as to Lessor's portion, *** per Site), and (ii) ***
               month's rent attributable to such new Site at a rate equal to the
               Arch Rate (to be paid only after Lessee has paid all rent
               attributable to such new Site for the following two (2) months);
               provided, however: (A) in no event shall the Relocation Allowance
               for a Site exceed the expenses actually incurred and paid to
               third parties and reasonably documented by Lessee in connection
               with such relocation; (B) Lessor's maximum aggregate Relocation
               Allowance obligation throughout the entire term of this Lease
               shall not exceed ***; and (C) Lessor's maximum

                                       3

               aggregate Relocation Allowance obligation during the third year
               of the term of this Lease shall not exceed ***, even if the
               aggregate Relocation Allowance amounts previously paid by Lessor
               during the term of this Lease are less than ***. Any Relocation
               Allowance owed hereunder will be paid by Lessor to Lessee, and
               may not be offset by Lessee against any of its obligations under
               this Lease. All Lessee Relocation Allowance claims hereunder,
               together with reasonable documentation evidencing that Lessee has
               incurred and paid the applicable relocation costs, shall be
               provided by Lessee to Lessor no later than one hundred twenty
               (120) days from the date such costs are incurred by Lessee, and
               shall be reimbursed by Lessor to Lessee in accordance with the
               terms hereof within thirty (30) days after Lessee's provision to
               Lessor of such claims and supporting documentation as Lessor may
               reasonably request.

          (g)  A Site Schedule will be prepared for every Site that is subject
               to this Lease. No later than the Effective Date (unless extended
               by mutual agreement of the parties), Site Schedules for all
               Existing Sites will be prepared, executed and delivered, and made
               a part of this Lease. Thereafter, a Site Schedule will be
               prepared, executed and delivered for each Site that for any
               reason becomes subject to this Lease. Each Site Schedule will be
               in substantially the form of the attached Exhibit C and will, as
               modified from time to time, also indicate (i) the description of
               Lessee's base station, Permitted Equipment and antenna systems,
               and the location thereof on a Site, (u) any special circumstances
               relating to a Site, (iii) the Site number assigned to the Site
               based on the chronological order in which such Site became
               subject to this Lease, (iv) Rent applicable to the Site from time
               to time (whether covered by the Base Rent, Acquired Site Rent,
               Excess Site Rent, Discovered Site Rent or otherwise as amended
               from time to time), (v) the Permitted Frequency (defined below)
               used by Lessee at the Site, (vi) whether the Site is a One-Way
               Site or a Two-Way Site, (vii) whether the Site includes a Link
               Transmitter Unit, a Hot Standby Unit, or an Excess Watt Unit
               and/or an Existing Microwave Unit (all as defined below), and
               (viii) the names and signatures of Lessor and Lessee (or their
               respective affiliates that constitute the applicable Site Lessor
               and Lessee) (collectively, as modified from time to time, the
               "Site Information"). The terms of the Site Schedules, as modified
               from time to time, will specifically identify such terms (but
               only such terms) as governed by the Site Schedules, but this
               Lease, as incorporated by reference into each Site Schedule, will
               otherwise govern.

          (h)  No later than the Effective Date and continuing through the term
               of this Lease, each of Lessor and Lessee shall appoint an
               Administrative Manager (defined below) to, on a monthly basis
               before the end of each month, reconcile and determine (i) the
               total number of Sites actually occupied by Lessee; (ii) the
               amount of Relocation Allowance then due and owing; (iii) any
               adjustments to Rent due to Removed Sites; (iv) the number of
               One-Way Sites, Two-Way Sites, Link Transmitter Units, Hot Standby
               Units, Net Excess Watt Units and/or Existing Microwave Units; and
               (v) such other matters as the parties may mutually agree. If the
               Administrative Managers are unable to reach agreement regarding
               any matter specified herein, such disagreement will be resolved
               as set forth in Section 23.

          (i)  Once each calendar quarter during the term of this Lease, Lessor
               will provide a quarterly review of all sites owned or operated by
               Lessor in its network, and all sites identified by Lessee that it
               uses in its business, with suggestions for potential Lessor sites
               to which Lessee may seek to relocate from non-Lessor sites. Each
               party will designate a qualified RF engineer or other technical
               support person to facilitate the foregoing.

          (j)  The parties agree that this Lease and the Site Schedules convey a
               leasehold interest in real estate and establish a landlord tenant
               relationship between the parties. Lessee reserves all of its
               rights as a tenant under 11 U.S.C. ss. 101, et seq. (the "Code"),
               including without limitation Section 365 of the Code.

                                       4

          (k)  Lessee may, from time to time on at least five (5) days written
               notice to Lessor, during the term of this Lease, eliminate one or
               more Sites and terminate the corresponding Site Schedule,
               provided, however, in the event that Lessee reduces the number of
               Sites below the Site Commitment in any applicable monthly period,
               Lessee shall, nonetheless, pay Lessor the Base Rent, Monthly
               Reservation Fee, Acquired Site Rent, and all other applicable
               Rent (as adjusted) for such period in accordance with the terms
               of this Lease. Notwithstanding the foregoing; the exercise by
               Lessee of its rights under this Section 1(k) will (i) if at such
               time Lessee has not met the Site Commitment, not result in any
               Rent reduction; (ii) if at such time Lessee has met the Site
               Commitment, result in an Excess Site Rent reduction, but in such
               case only as set forth in the following sentence. If Lessee seeks
               to eliminate a Site that at the time was counted toward the Site
               Commitment and for which the Rent obligation was covered by the
               Base Rent and Monthly Reservation Fee, then if the eliminated
               Site is (A) a One-Way Site, of the One-Way Sites leased under
               this Lease in excess of the Site Commitment and being paid for by
               Excess Site Rent, the One-Way Site having the earliest Site
               Schedule date will then be counted toward the Site Commitment and
               covered by the Base Rent and Monthly Reservation Fee, or (B) a
               Two-Way Site, of the Two-Way Sites leased under this Lease in
               excess of the Site Commitment and being paid for by Excess Site
               Rent, the Two-Way Site having the earliest Site Schedule date
               will then be counted toward the Site Commitment and covered by
               the Base Rent and Monthly Reservation Fee.

     2.   TERM:

          (a)  The initial term of this Lease shall be three (3) years from the
               Effective Date of this Lease. Upon expiration of the initial
               term, this Lease may be renewed on such terms and conditions as
               the parties mutually agree, in their respective sole discretion.

          (b)  If Lessee holds over with respect to any Site(s) after expiration
               of the Lease term, the Lease term with respect to such Site(s)
               shall revert to a month-to-month term, and rent shall be 125% of
               the Rent applicable to such Site(s) during the last month of the
               preceding term (if there is no specific rental rate applicable to
               the particular Site, the holdover rent shall be 125% of the Arch
               Rate). Lessor and Lessee shall each have the right during such
               month-to-month term to terminate the Lease term with respect to
               such hold over Site(s) without cause upon thirty (30) days notice
               to the other party, unless a shorter period is required by an
               applicable Prime Agreement.

     3.   RENT:

          (a)  Lessee shall pay rent during the term of this Lease comprising a
               monthly reservation fee (the "Monthly Reservation Fee"), plus a
               base rent amount ("Base Rent"), as follows:

               (i)  the Monthly Reservation Fee shall be (A) *** per month
                    during the first year of the term hereof; and (B) *** per
                    month during the second and third years of the term hereof;
                    and

               (ii) the Base Rent shall be (A) *** per month during the first
                    year of the term hereof; (B) *** per month during the second
                    year of the term hereof; and (C) *** per month during the
                    third year of the term hereof.

               The Base Rent, the Monthly Reservation Fee, the Acquired Site
               Rent, the Excess Site Rent (defined below), and the Discovered
               Site Rent (defined below), are collectively referred to as "Rent"
               as adjusted. Rent shall be paid in advance on a monthly basis,
               commencing on the first full day of the full calendar month first
               occurring after the Effective Date and continuing on the first
               day of each month thereafter during the term hereof.

                                       5

               The Base Rent, Monthly Reservation Fee and Acquired Site Rent
               shall be owed by Lessee to Lessor without regard to whether the
               actual number of Sites leased or occupied by Lessee, or whether
               Lessee has met the Site Commitment, and without offset or
               reduction in any manner, except as expressly provided herein
               regarding undisputed Removed Sites and regarding undisputed
               Relocation Allowance amounts. The Monthly Reservation Fee shall
               be paid by Lessee to Lessor for Lessor's agreement to allow
               Lessee to add Additional Sites, in accordance with the terms
               described elsewhere herein. All of the fees and costs associated
               therewith shall be deemed included in the Monthly Reservation
               Fee.

          (b)  If Lessee occupies a number of Sites in excess of the applicable
               Site Commitment, Lessee will be obligated to pay Lessor rent for
               all such excess Sites (the "Excess Site Rent") on the same date
               as all other Rent is paid and in addition thereto, an amount
               equal to the following rate per excess Site (the "Arch Rate").

               (A) For each One-Way Site: *** per month (provided the *** per
               month rate shall be increased to *** effective July 1, 2003 and
               to *** effective July 1, 2004), except if a Net Excess Watt Unit
               is used at a One-Way Site the rate shall be *** per month for
               Site (provided the *** per month rate shall be increased to ***
               effective July 1, 2003 and to *** effective July 1, 2004).

               (B) For each Two-Way Site: *** per month (provided the *** per
               month rate shall be increased to *** effective July 1, 2003 and
               to *** effective July 1, 2004).

          (c)  If a Site becomes a Removed Site and the Removed Site Conditions
               are satisfied regarding such Removed Site, then subject to and in
               accordance with the terms of this Section 3(c), the applicable
               portion of the Rent otherwise owed for such Site shall not be
               owed, commencing effective on the date on which such Site became
               a Removed Site hereunder. If a Site becomes a Removed Site as
               provided herein under the circumstances described in: (i) Section
               1(d), then the applicable portion of the Rent for such Removed
               Site shall be reduced in an amount equal to the greater of the
               Arch Rate, or if as a result of such removal and lack of a
               Replacement Site Lessee relocates to a Functionally Equivalent
               non-Lessor site, the average of the Arch Rate and the rate paid
               by Lessee for such non-Lessor site; (ii) in Sections 5(d)(ii),
               10(a) and 10(b), 11 or 21(a), if the Site Commitment is (A) met
               at the time, the Excess Site Rent for such Removed Site shall not
               be owed, or (B) not met at the time, the applicable portion of
               the Rent for such Removed Site shall be reduced by the Pro Rata
               Amount (defined in Section 24).

          (d)  From and after the date that is three (3) months after the
               Effective Date, if either party learns of or discovers that
               Lessee has equipment at a space on a Site hereunder or on a site
               elsewhere in Lessor's network, and such space or site is not then
               described in and subject to a Site Schedule as a Site under this
               Lease but was occupied by Lessee before the Effective Date (a
               "Discovered Site"), Lessor or Lessee, as the case may be, will
               provide prompt notice in writing to the other party of such
               Discovered Site, together with a description of the equipment
               thereon. If at such time Lessee has met the minimum Site
               Commitment, Lessee shall be required to pay rent for such
               Discovered Site to Lessor ("Discovered Site Rent") for the period
               beginning retroactively to the Effective Date until Lessee
               removes its equipment from the Discovered Site, at a monthly rate
               equal to (1) 75% of the Arch Rate if Lessee first notifies Lessor
               of the Discovered Site, or (2) 125% of the Arch Rate if Lessor
               first notifies Lessee of the Discovered Site. Within thirty (30)
               days following the date a party provides written notice hereunder
               of a Discovered Site, Lessee, at its option, must either remove
               the subject equipment and restore such Discovered Site to its
               original condition, normal wear, tear and Casualty excepted, or
               enter into a Site Schedule for such Discovered Site. If a Site
               Schedule is entered into for a Discovered Site, such site shall
               constitute a Site hereunder and shall be included in the
               calculation of the applicable Site Commitment.

                                       6

          (e)  Lessee shall pay all amounts that are due and owing to Lessor
               hereunder by wire transfer or ACH credit to Lessor's account as
               identified by Lessor, or at Lessee's option, by Lessor ACH debit
               of Lessee's account as identified by Lessee, no later than the
               first business day of each calendar month with respect to which
               it is payable. If payment (including any applicable late fee) is
               not received when due, Lessor has the option to charge a late fee
               equal to 5/6% per month of the amount due, but no such late fee
               will apply to reasonably disputed charges.

          (f)  Lessee shall pay all sales or use taxes, fees, and assessments
               applicable to Rent or as a direct result of Lessee's equipment
               being located on or Lessee's use of the Leased Premises, but in
               no event shall Lessee be responsible for any local, state or
               federal capital levy, franchise tax, or revenue tax on profits of
               Lessor.

          (g)  As part of the consideration hereunder, throughout the term of
               this Lease, Lessee shall provide at no charge to Lessor, ten (10)
               two-way paging devices and related paging services in the 50,000
               character/month per device (with $.0006 character/month charge
               for excess usage). The use of such devices will be subject to
               Lessee's standard terms and conditions.

     4.   INSTALLATION:

          (a)  Lessee shall install only the Permitted Equipment identified in
               the Site Schedules, and the cost of Lessee's installation,
               including the cost of any permits or licenses required for such
               operation, shall be borne solely by Lessee. Lessee shall comply
               with all Site rules and standards contained in Exhibit A to this
               Lease, each of which are incorporated herein by this reference.

          (b)  During installation, Lessee shall not cause interference of any
               kind to the activities of Lessor or other Lessees on the Site. If
               such interference is caused by Lessee and cannot, within ten (10)
               days after written notice from Lessor to Lessee, be reduced to
               levels reasonably acceptable to Lessor, then Lessee shall
               immediately halt all installation work, and Lessor may elect to
               terminate the applicable Site Schedule by giving Lessee ten (10)
               days written notice, but in such event, such Site will not be
               deemed a Functionally Equivalent Site or Replacement Site.

          (c)  The placement of any slab and/or building for Lessee's use at a
               Site must be pre-approved by Lessor, in Lessor's sole discretion,
               prior to installation. All pre-installation thereof shall be
               coordinated through the Lessor's appointed representative for
               said Site. No changes to the placement will be allowed without
               the prior written approval of Lessor, in Lessor's sole
               discretion. Lessee shall be solely liable for all expenses,
               permits and licenses related to installation thereof as well as
               the cost to enclose Lessee's equipment.

          (d)  Lessor reserves the right to require Lessee to relocate any or
               all of Lessee's equipment within a Site, and Lessee agrees to
               relocate said equipment, provided that (i) Lessor shall pay the
               reasonable cost of such relocations, and (ii) said relocation
               does not render the operations on the Site functionally
               non-equivalent to Lessee's prior operations thereon. If the
               parties dispute whether any such relocation renders the Site
               functionally non-equivalent to Lessee's prior operations thereon,
               and Lessor does not provide a Replacement Site accepted by
               Lessee, then such dispute shall be resolved in the manner set
               forth in Section 23.

          (e)  Prior to entering into a Site Schedule for a Site, upon providing
               Lessor at least two (2) business days prior notice, Lessee shall
               have the right to conduct reasonable tests, studies and analyses
               of the prospective Site in order to determine the suitability of
               such Site for Lessee's intended use. All such investigations
               shall be performed at Lessee's expense, Lessee shall restore the
               Site to its original condition (reasonable wear, tear and
               Casualty

                                       7

               excepted), and Lessee shall be liable for, and shall indemnify
               Lessor against, any damages resulting from the investigations. No
               such investigation shall be permitted to disturb existing tenants
               at the Site, and any investigations Lessor and Lessee shall abide
               by the entry and testing terms set forth on the attached Exhibit
               D and the requirements of Section 5(c). Before any such
               investigations, Lessee and its vendors must provide Lessor
               evidence reasonably satisfactory to Lessor of insurance as
               required pursuant to the attached Exhibit B.

     5.   USES OF LEASED PREMISES:

          (a)  Lessee shall use the Leased Premises and conduct its
               communications operations in compliance with the terms of its FCC
               license, and all applicable laws, orders, ordinances, and
               regulations pertaining to the Leased Premises or Lessee's
               business. Lessee shall, if requested, provide Lessor with copies
               of all permits and FCC licenses required in connection with
               Lessee's operations on the Leased Premises.

          (b)  Lessee shall have a non-exclusive right to access the Leased
               Premises twenty-four (24) hours a day, 365 days a year for its
               employees, agents, or representatives as designated, subject to
               reasonable security restrictions and subject to the terms of
               applicable Prime Agreements of which Lessor has provided Lessee
               notice (including any payments to lessors under Prime Agreements
               of which Lessor has provided Lessee notice required as a result
               of Lessee's access, which Lessee shall bear). In accordance with
               procedures in Exhibit A, Lessee will be issued a key, key card,
               and/ or access code to unlock the gate and transmitter room for
               maintenance purposes. This key may not be duplicated, loaned, or
               transferred to any other entity. If this key or keycard is lost
               or the integrity of security is breached by Lessee, Lessee will
               bear the expense for and cost actually incurred and paid to third
               parties by Lessor to re-tool the locks, reprogram the security
               system, and provide new keys and/or keycards for all authorized
               persons. Lessee shall provide Lessor the name of Lessee's
               custodian of the key or keycard; should the custodian change,
               Lessee shall notify Lessor, in writing, of the new custodian's
               identity within three (3) business days.

          (c)  Before performing any installation or maintenance work at a Site,
               Lessee shall notify Lessor and (i) if such work involves activity
               on or directly about a tower on the Site, Lessee shall be
               required to obtain Lessor's consent to the work and the persons
               to perform the work before commencing any such work, which
               consent Lessor may withhold in Lessor's commercially reasonable
               discretion; (ii) if such work does not involve activity on or
               directly about a tower on the Site, Lessee shall be required to
               obtain Lessor's consent to the work and the persons to perform
               the work before commencing such work, which consent shall not be
               unreasonably withheld. Notwithstanding the foregoing, if such
               work (1) does not involve activity directly on or about a tower
               on the Site and constitutes only minor routine maintenance,
               installation, removal, modification or other permitted changes of
               Permitted Equipment, or Permitted Frequency changes that in any
               event do not involve activity on or directly about a tower on the
               Site, then Lessee may perform such work without Lessor's prior
               consent so long as Lessee provides Lessor prior notice thereof;
               or (2) is required as a result of an emergency and does not
               involve activity directly on or about a tower on the Site, Lessee
               shall only be required to use commercially reasonable efforts to
               provide Lessor prior notice of such work. Subject to the
               foregoing, all contractors and subcontractors of Lessee who
               perform any services on the Leased Premises must (i) be approved
               by Lessor in advance, (ii) hold all licenses necessary for the
               work being performed, (iii) provide evidence reasonably
               satisfactory to Lessor of insurance required pursuant to the
               attached Exhibit B, and (iv) provide in form acceptable to Lessor
               either lien waivers or releases of Lessor. All installation and
               maintenance work must comply with the requirements of the
               attached Exhibits A and B. Notwithstanding the foregoing, without
               Lessor's prior consent, which consent Lessor may withhold in
               Lessor's sole discretion, neither Lessee nor any of its
               representatives may

                                       8

               perform any maintenance, repairs or other work with respect to
               any tower itself, or other Lessor property on any Site.

          (d)  (i) Lessee shall not cause interference of any kind to the
               operations of the Lessor (if Lessor is then using equipment on
               the applicable Site(s)) or other Lessees that are then-current
               tenants at the applicable Site(s) in excess of levels permitted
               by the FCC, as well as interference to consumer electronic
               devices and blanketing interference as defined by section 73.318
               of the FCC rules. Subject to this Section 5(d), Lessee's
               equipment (including any subsequent modification or alteration
               thereto) shall be conducted in a manner that does not interfere
               electrically, or in any other manner whatsoever known at the time
               by Lessee with any then pre-existing use of by Lessor or other
               users of the on a Site that pre-exists the installation of
               Lessee's equipment at such location ("Pre-Existing Use"). In the
               event that any Pre-Existing Use experiences interference caused
               by Lessee's equipment (including any subsequent modification or
               alteration thereto), Lessee shall be notified in writing of such
               interference and Lessee shall power-down its equipment and/or
               cease operations in order to correct and eliminate such
               interference within seventy-two (72) hours after Lessee's receipt
               of such notice. If Lessee does not cease all interfering
               operation within such seventy-two (72) hour period, Lessee shall
               power-down the offending equipment at the applicable Site. Lessee
               shall have the right to test its equipment from time to time or
               at any time to attempt to correct the problem. If Lessee is
               unable to eliminate the interference, or reduce it to a level
               acceptable to the affected user of the Pre-Existing Use, within a
               period of thirty (30) days following such initial notice
               (provided that during such thirty (30) day period, Lessee may
               operate its equipment intermittently for testing purposes only),
               then Lessor may terminate the applicable Site Schedule. In the
               event that Lessee is notified of any interference experienced by
               a Pre-Existing Use on the applicable Site alleged to be caused by
               Lessee's equipment thereon, Lessee shall make commercially
               reasonable efforts, at Lessee's sole cost and expense, to
               eliminate such interference and shall not be released from its
               obligation to continue to pay its applicable rents during any
               testing period that Lessee cannot operate from such Site, unless
               and until the Site Schedule is terminated by either the Lessor or
               the Lessee. If Lessee is required to discontinue its operation
               under this Subsection 5(d)(i) due to interference with a
               Pre-Existing Use for a period of sixty (60) days, then Lessor
               shall have the right to terminate this Lease only as to the
               subject Site Schedule, but such termination shall not result in
               the Site being deemed a "Removed Site"

               (ii) Lessor agrees that Lessor and Lessor's customers' use of the
               applicable Site with respect to equipment that is installed or
               modified subsequent to Lessee's then-current operation of
               Lessee's equipment thereon ("Subsequent Use") will not interfere
               with Lessee's then-current operations. In the event that Lessee
               experiences interference caused by any Subsequent Use, Lessee
               shall notify Lessor in writing or telecopy of such interference
               and Lessor shall, or shall cause the operator of the interfering
               Subsequent Use to, power-down its equipment and/or cease
               operations in order to correct and eliminate such interference
               within seventy-two (72) hours after such Subsequent Use's receipt
               of such notice. If such Subsequent Use results in Lessee being
               unable to operate without causing such interference, or if such
               interference is not reduced to a level reasonably acceptable to
               Lessee, within a period of thirty (30) days (provided that during
               such thirty (30) day period the Subsequent Use may be operated
               intermittently for testing purposes only), then Lessee may
               terminate the applicable Site Schedule. If Lessee is required to
               discontinue its operation under this Section 5(d)(ii) due to
               interference with a Subsequent Use for a period of thirty (30)
               days, and no Replacement Site for the affected Site has by then
               been accepted by Lessee, then Lessee shall have the right to
               terminate this Lease only as to the subject Site Schedule, and
               such termination shall result in the Site being deemed a "Removed
               Site" provided the Removed Site Conditions are satisfied. Lessor
               will use commercially reasonable efforts to cause any such
               interfering Subsequent Use to cease any interfering operations in
               accordance with this Section 5.

                                       9

               (iii) If harmful interference is caused in whole or in part by
               Lessee to the equipment of others not specifically designed to
               transmit, receive and/or use radio frequency energy, Lessee shall
               be obligated to reduce or eliminate such harmful interference as
               provided by FCC Rules Parts 22, 24, 90, and 15.

          (e)  Lessee shall cooperate with Lessor in its reasonable rescheduling
               of transmitting activities, reducing power, or interrupting its
               activities for limited periods of time in order to permit the
               safe installation of new equipment or new facilities at the Sites
               or to permit repairs to facilities of any user of the Sites or to
               the Sites or related facilities.

          (f)  Lessor makes no guaranty or warranty, including any implied
               warranty of merchantability or fitness for a particular use.

          (g)  Lessee may only operate Permitted Frequencies (defined below) at
               Sites under this Lease. Upon prior written notice received by
               Lessor not less than the greater of five (5) business days or the
               advance notice contained in Lessor's underlying Prime Agreement
               plus three (3) business days (provided that Lessor has provided
               Lessee with the relevant provisions of the underlying Prime
               Agreement), subject to the other terms and conditions of this
               Lease and the terms of applicable Prime Agreements, so long as
               the Site Frequency Change Conditions (defined below) are
               satisfied, Lessee shall be permitted to add and operate
               additional frequencies, and/or change the frequencies, operating
               on its telecommunications equipment located on a Site. Lessee
               shall be permitted to do the foregoing for no additional Rent for
               so long as the Site Frequency Change Conditions are satisfied. If
               the Site Frequency Change Conditions are not satisfied, then
               Lessee must obtain Lessor's prior written consent to consummate
               such change, which consent may be withheld in Lessor's sole
               discretion. If Lessor approves any such change, the applicable
               Site Schedules (including the appropriate Rent for such Site)
               shall be amended a appropriate. Whether or not operating on FCC
               authorized paging channels as defined in the "Permitted
               Equipment" definition herein, Lessee agrees that its operations
               on all such frequencies will have the characteristics of the
               defined "One-Way Site" and/or "Two-Way Site" hereunder.

          (h)  If after the Effective Date Lessee proposes that a New Link
               Transmitter Unit (defined below) be included on a Site , Lessee
               shall pay to Lessor for each such New Link Transmitter Unit an
               amount equal to *** per month. Such amount shall not be owed with
               respect to Existing Link Transmitter Units (defined below). Such
               amount shall be the only rent payable for a Site that consists
               exclusively of a New Link Transmitter Unit. For Sites that
               consist of a New Link Transmitter Unit together with a One-Way
               Site or a Two-Way Site, such amount shall be payable in addition
               to the rent otherwise payable for such One-Way Site or Two-Way
               Site. For the purpose of determining whether the Site Commitment
               is met, an Existing Link Transmitter Unit shall constitute a
               'Site' under this Lease, but a New Link Transmitter Unit shall
               not constitute a "Site" under this Lease. Therefore, if an
               Existing Link Transmitter Unit is used by Lessee (i) independent
               of a One-Way Site or a Two-Way Site, it will be deemed one (1)
               Site, (ii) in connection with a One-Way Site, the Link
               Transmitter Unit and the One-Way Site together will be deemed two
               (2) Sites, or (iii) in connection with a Two-Way Site, the Link
               Transmitter Unit and the Two-Way Site together will be deemed
               three (3) Sites.

          (i)  Lessee shall pay Lessor an additional *** per month for the
               aggregate amount of Net Excess Watt Units (defined below) that
               exist during each month, in addition to all Rent obligations.
               Lessee shall provide Lessor prior written notice of Lessee's use
               of an Excess Watt Unit at any Site, except in the case of Excess
               Watt Units located as of the Effective Date on Existing Sites.

          (j)  Lessee shall not install, use or operate any Site under this
               Lease except as a One-Way Site or a Two-Way Site.

                                       10

          (k)  Except for Permitted Equipment, Lessee may not load equipment at
               a Site without Lessor's express prior written consent, which
               consent may be withheld in Lessor's sole discretion. If Lessee
               loads any equipment without a required consent from Lessor,
               Lessee shall be in breach with respect to such Site.
               Notwithstanding the restriction in the "Two-Way Site" definition
               to a single transmitter, Lessee shall be permitted to have, on up
               to 185 Existing Sites as of the Effective Date, up to two (2)
               transmitters thereon, provided such transmitters are located
               within existing cabinets on such Sites as of the Effective Date
               and provided Lessee pays Lessor in addition to all other amounts
               owed for such Sites an amount equal to *** per month for each
               such additional transmitter on such Existing Sites.
               Notwithstanding the foregoing, Lessee shall not be permitted to
               have more than two (2) transmitters on a Site.

     6.   UTILITIES: Lessee shall pay all installation costs for electrical
          power feeds and phone lines to its equipment. Lessee shall pay for all
          Lessee's electrical power usage at Existing Sites for which Lessor is
          not already responsible for the payment of under a Prior Lease
          (defined below), either directly to the utility company or as a
          reimbursement to Lessor. Lessor shall pay for the actual costs of
          Lessee's electrical power usage at all other Sites. In no event will
          Lessor pay for any telephone or other utility charges or costs of
          Lessee or related to Lessee's operation at Sites hereunder.

     7.   INSURANCE:

          (a)  Insurance requirements for Lessee and Lessee's contractors are
               contained in Exhibit B attached hereto and incorporated herein by
               this reference.

          (b)  Lessor and Lessee release each other, and their respective
               principals, employees, representatives and agents, from any
               claims for damage to any person or to the Leased Premises, the
               Sites and any improvements thereon, that are caused by, or result
               from, risks insured against under any insurance policies carried
               by the parties and in force at the time of any such damage and
               any risks which would be covered by the insurance which such
               party is required to carry hereunder. Each party will cause each
               insurance policy obtained by it to provide that the insurance
               company waives all right of recovery by way of subrogation
               against the other party in connection with any damage covered by
               any policy.

     8.   MAINTENANCE OF SITE:

          (a)  Lessor shall maintain the Sites in good repair, ordinary wear,
               tear and Casualty excepted, and, to the extent applicable as
               determined by Lessor, in compliance with applicable sections of
               FAA regulations, and Part 17 of FCC regulations pertaining to
               lighting, marking, inspection, and maintenance. In cases where
               such FCC regulations require the painting of Lessee's feedlines,
               Lessee hereby consents to such painting.

          (b)  Lessee shall maintain its equipment in accordance with standards
               of good engineering practice to assure that it conforms with the
               site standards identified in Exhibit A which standards are
               attached hereto and incorporated herein by this reference, and
               shall surrender possession of the Leased Premises to Lessor in
               the same condition they were at the commencement of this Lease,
               ordinary wear, tear and Casualty excepted. Lessee shall place at
               the Leased Premises such signs as may be required by applicable
               federal, state, or local law with respect to Lessee's equipment.

          (c)  All radio frequency emission ("RFE") analyses whether conducted
               by Lessor or Lessee will comply with guidelines and procedures
               for evaluating environmental effects of RF emissions on or from
               the applicable Site, in strict compliance with FCC OET Bulletin
               65, entitled Evaluating Compliance with FCC Guidelines for Human
               Exposure to Radio frequency Electromagnetic Fields, Edition
               97-01, released August 1997 ("OET Bulletin

                                       11

               65"), and all existing and future laws, rules, and regulations
               related thereto (collectively, "EMF Rules"). Lessor agrees to
               make available to Lessee such information, reports and data if
               and to the extent prepared by Lessor in connection with radio
               frequency emission analyses (RFE Analyses) related to Sites. Such
               information, if any, may include, without limitation, RFE
               software simulation analyses, reports of on site FIFE measurement
               survey results, and the Health and Safety plan for the Site,
               including identification of access limitations and signage
               required to control access to areas where Maximum Permissible
               Exposures (MPE) are exceeded for the relevant standards, whether
               such RFE Analyses were performed by Lessor or by a reliable third
               party. If Lessor is unable to, or otherwise does not, provide RFE
               Analyses for a Site, Lessee may prepare an analysis at its sole
               expense. In such cases, Lessor agrees to provide, to the extent
               available, any relevant information it may have relating to the
               preparation of the analysis, and will cooperate with regard to
               scheduling and third-party site user notification(s).

               Notwithstanding the foregoing, Lessor and Lessee agree that
               Lessee installations meeting the following minimum criteria shall
               not require RFE analysis unless otherwise mandated by a
               governmental authority having jurisdiction:

               (i) One-Way or Two-Way Site having all antenna(s) mounted at
               least 100 feet above any area subject to public or transitory
               use; or

               (ii) Radio frequency energy attributed to Lessee's
               installation(s) on the Site can be calculated to be within FCC
               specified safe limits (using the procedures outlined in FCC
               Bulletin OET-65, as revised);

               (iii) Installations that are categorically excluded from the
               requirement to meet RFE requirements per the governmental agency
               having jurisdiction.

     9.   ALTERATION BY LESSEE:

          (a)  Lessee may not make improvements or alterations to any Site,
               tower, building, or any other portion of the Leased Premises
               without the express written permission of Lessor, in Lessor's
               sole discretion. Any such improvements that are approved by
               Lessor and thereafter made by Lessee shall at Lessor's option
               become the property of Lessor upon termination or expiration of
               this Lease, but the foregoing will not limit Lessor's right to
               require removal of such equipment upon termination or expiration.

          (b)  Subject to the installation, use and other restrictions set forth
               in this Lease or any Prime Agreement, upon providing Lessor ten
               (10) days prior written notice (but such prior notice shall not
               be required for changes and alterations consisting of Permitted
               Equipment), Lessee may make changes and alterations in its
               equipment provided that (i) such changes or alterations conform
               with standards of good engineering practice and the provisions of
               Section 5, (ii) plans and specifications are first submitted to
               and approved in writing by Lessor, which approval shall not be
               unreasonably withheld, and (iii) any proposed changes or
               alterations do not increase the "wind loading" (per EIA Standard
               RS-22F or as revised) or stress of the applicable tower or
               require Lessee's use or occupancy of any additional space at the
               subject Site. At Lessor's request, Lessee will provide an
               independent professional analysis of "wind loading" and stress to
               determine any changes that equipment replacements or alterations
               would cause.

     10.  SITE DAMAGE; DAMAGE TO LESSEE'S EQUIPMENT:

          (a)  If a Site is fully or partially destroyed or damaged, Lessor, at
               its option, may elect to terminate the Lease with respect to such
               Site, or Lessor may relocate Lessee to another site in Lessor's
               network, upon ten (10) days written notice to the Lessee.
               However, if as a

                                       12

               result of such damage or destruction Lessee is unable to conduct
               its operations on such Site in a manner that is functionally
               equivalent to Lessee's operations before such event, and the
               Removed Site Conditions have been satisfied and the damage or
               destruction occurred through no fault of Lessee, then such Site
               will be deemed a "Removed Site."

          (b)  Lessor, at its option, may elect to repair or rebuild the Site,
               in which case, this Lease including the applicable Site Schedule
               shall remain in force with respect to such Site. If
               reconstruction or repair cannot reasonably be undertaken without
               dismantling Lessee's antenna, then Lessor may remove Lessee's
               antenna and interrupt Lessee's operations, thereafter replacing
               the antenna as soon as reasonably possible, but in no event later
               than ten (10) days after such dismantling, following which if
               such Site is not fully operational to Lessee's reasonable
               satisfaction in a manner that is functionally equivalent to
               Lessee's operations before such event, Lessor shall use
               reasonable efforts to identify a suitable Replacement Site for
               the affected Site, and if no Replacement Site has been accepted
               by Lessee within fifteen (15) days (which period may be extended
               by mutual agreement of the parties) after expiration of such ten
               (10) day period, and the Removed Site Conditions have been
               satisfied, then Lessee may designate such site as a "Removed
               Site."

          (c)  Under no circumstances whatsoever shall Lessor be responsible for
               damage to or loss of Lessee's equipment, or for financial loss
               due to business interruption.

          (d)  Lessor shall incur no liability to Lessee for failure to furnish
               space and/or electrical power if prevented by war, fires,
               accidents, labor strikes, acts of God, or other causes beyond its
               reasonable control.

     11.  EMINENT DOMAIN: If the land or Leased Premises upon which a tower,
          foundation, or building is located are acquired or condemned under the
          power of eminent domain, whether by public authority, public utility,
          or otherwise, and as a result thereof Lessee is unable to conduct its
          operations on such Site in a manner that is functionally equivalent to
          Lessee's operations before such event, Lessee shall notify Lessor
          thereof. Lessor shall use reasonable efforts to identify a suitable
          Replacement Site for the affected Site, and if no Replacement Site has
          been accepted by Lessee within fifteen (15) days (which period may be
          extended by mutual agreement of the parties) after receipt of notice
          from Lessee, and at the time of such event the Removed Site Conditions
          have been satisfied, then the Site shall be deemed a "Removed Site".

     12.  INDEMNIFICATIONS:

          (a)  Lessee shall indemnify, hold harmless, and defend Lessor for and
               against any and all liabilities, claims, demands, suits, damages,
               actions, recoveries, judgments, and expenses (including court
               costs, reasonable attorneys' fees, and costs of investigation)
               resulting from injury to or death of any person or any damage to
               property, or loss of revenues due to any breach of this Lease or
               any Site Schedule by Lessee, or any negligent act or omission, or
               willful misconduct of Lessee or its contractors, subcontractors,
               agents, or representatives occurring in or around the Leased
               Premises, except to the extent such liabilities are directly
               caused by the willful misconduct or gross negligence of Lessor.

          (b)  Lessor shall indemnify, hold harmless, and defend Lessee for and
               against any and all liabilities, claims, demands, suits, damages,
               actions, recoveries, judgments, and expenses (including court
               costs, reasonable attorneys' fees, and costs of investigation)
               resulting from injury to or death of any person or any damage to
               property, or loss of revenues due to any breach of this Lease or
               any Site Schedule by Lessor, or any negligent act or omission, or
               willful misconduct, of Lessor or its contractors, subcontractors,
               agents, or representatives occurring in or around the Leased
               Premises, except to the extent such liabilities are directly
               caused by the willful misconduct or gross negligence of Lessee.

                                       13

          (c)  NOTWITHSTANDING THE FOREGOING OR ANY OTHER PROVISION OF THIS
               LEASE OR ANY SITE SCHEDULE TO THE CONTRARY IN NO EVENT SHALL
               EITHER PARTY BE RESPONSIBLE FOR, OR LIABLE FOR ANY LOSS, COST,
               DAMAGE, EXPENSE, INJURY OR OTHER LIABILITY WHICH IS IN THE NATURE
               OF INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES WHICH
               ARE SUFFERED OR INCURRED AS THE RESULT OF, ARISE OUT OF, OR ARE
               IN ANY WAY CONNECTED TO THE PERFORMANCE OF OBLIGATIONS HEREUNDER.

     13.  SUBLETTING; ASSIGNMENT; SUCCESSION:

          (a)  Lessee shall not assign this Lease or any Site Schedule in whole
               or in part, or sublet or permit the Leased Premises or any part
               thereof to be used by others without the express written approval
               of Lessor in its sole discretion; and Lessee shall not mortgage
               or encumber this Lease without the express written approval of
               Lessor, which consent shall not be unreasonably withheld or
               delayed. No assignment, sublease or authorized use by others
               shall relieve Lessee of its obligations under this Lease. Lessor
               may assign, mortgage, or encumber its rights under this Lease at
               any time. Notwithstanding the foregoing, (i) Lessee may assign
               this Lease and all Site Schedules to any person or entity that
               Lessor in its sole discretion deems to be financially acceptable,
               and (ii) Lessee shall have the right, without Lessor's prior
               consent, whether written or oral, to assign its rights and
               obligations under (A) this Lease and all Site Schedules to any
               affiliate or successor in interest (by whatever means) to
               substantially all of the assets of Lessee, and (B) individual
               Site Schedules to any affiliate of Lessee, so long as in either
               case the assignee assumes all liabilities and obligations under
               this Lease and the Site Schedules. In no such event shall Lessee
               be relieved of any liability or obligations under this Lease or
               any Site Schedules.

          (b)  If Lessee becomes a successor in interest to occupancy rights in
               sites owned or operated by Lessor ("Lessee Acquisition"), or if
               Lessor becomes successor in interest to any sites upon which
               Lessee is then-currently leasing ("Lessor Acquisition"), pursuant
               to a lease between Lessee or Lessor, as applicable, and the
               respective tenant or landlord, as applicable (an "Acquired
               Lease") then all of the Sites subject to such Acquired Lease
               ("Acquired Sites") shall be come "Sites" subject to and leased
               under this Lease. However, notwithstanding anything to the
               contrary set forth in this Lease, in no such event shall Acquired
               Sites be included in the calculation of or otherwise counted
               toward the Site Commitment, and in no event shall the rental
               obligation for Acquired Sites be covered by the Base Rent or
               Monthly Reservation Fee. In connection with any Lessee
               Acquisition or Lessor Acquisition:

               (i) To the extent any Acquired Site does not on the date of such
               acquisition comply materially with the non-monetary provisions of
               this Lease, Lessee shall bring such Acquired Site into material
               compliance with this Lease, and any failure of Lessee to do so
               will constitute a breach of this Lease as to the applicable
               Acquired Site only;

               (ii) the Acquired Lease shall be incorporated into and made
               subject to this Lease; and

               (iii) the rent for Acquired Sites shall be the Acquired Site
               Rent, which shall be owed, in addition to the Base Rent and
               Monthly Reservation Fee. The Acquired Site Rent shall be
               increased by three percent (3%) per annum for each Acquired Site
               as of each anniversary date of the acquisition of such Acquired
               Site.

               Such Acquired Site Rent shall be owed by Lessee for the Acquired
               Sites in addition to the Base Rent and Monthly Reservation Fee,
               regardless of whether or not Lessee has met the Site Commitment.
               In any such event, a new Site Schedule will be executed and
               incorporated into this Lease for each Acquired Site. Neither
               Lessor nor Lessee will

                                       14

               unreasonably withhold or delay its consent, if such consent is
               required, to any such acquisition or other transaction in which
               Lessor or Lessee succeeds to interest(s) in Acquired Leases and
               Acquired Sites.

          (c)  Notwithstanding the provisions of Section 13(b)(iii) and
               13(b)(iv) above, if there exists a reasonable dispute regarding
               any Acquired Site Rent or Base Acquired Site Rent, such dispute
               shall be resolved as set forth in Section 23, and during the
               pendency of any such dispute, Lessee shall only be obligated to
               pay 85% of the Arch Rate for such Acquired Site. Upon resolution
               of such dispute, if the rent actually owed (i) exceeds the amount
               paid pursuant to this Subsection 13(c), Lessee shall pay to
               Lessor the balance owed within 30 days of such resolution; or
               (ii) is less than the amount paid pursuant to this Subsection
               13(c), Lessor shall refund to Lessee the overpayment, within 30
               days of such resolution.

     14.  DEFAULT:

          (a)  Monetary Default: A party shall be in default hereunder if it
               fails to make any payment within ten (10) days of date due and
               does not cure such non-payment within five (5) days after a
               non-defaulting party provides the defaulting party written notice
               thereof.

          (b)  Non-Monetary Default: A party shall be in default hereunder if it
               fails to comply with any other term of this Lease or any Site
               Schedule and does not cure such other failure within thirty (30)
               days after a non-defaulting party provides the defaulting party
               with written notice thereof; provided however, that if any such
               non-monetary default is not capable of being cured within the
               requisite period of time, then so long as the party charged with
               the default has diligently pursued such cure of the default
               within the prescribed period, such party shall be given the
               necessary time to cure the default, such time not to exceed
               ninety (90) days, unless a shorter period is expressly required
               under the terms of this Lease.

          (c)  Certain Lessor Remedies: If subsequent to the foregoing requisite
               periods of time as applicable, there continues to be an event of
               default, Lessor may exercise any or all of the following
               remedies, in addition to all other remedies available to Lessor
               under this Lease or otherwise provided at law or in equity:

               (i) terminate this Lease and all Site Schedules and declare the
               entire balance of all forms of Rent (other than any reasonably
               disputed Excess Site Rent) due under this Lease for the remainder
               of the term to be immediately due and payable, in which event
               Lessee shall promptly surrender possession of the Leased
               Premises, and Lessee shall be liable for all past due amounts
               under this Lease, plus the amount of the Rent and other benefits
               that Lessor would have received for the remainder of the current
               term of the Lease; however, if at such time Lessee has met the
               Site Commitment and paid all Rent other than the reasonably
               disputed Excess Site Rent then due, then Lessor may terminate,
               accelerate and/or seek damages only with respect to (1) those
               Site Schedules for which there is any default, whether for
               failure to pay Excess Site Rent or otherwise, and (2) a number of
               additional Site Schedules, chosen by Lessor in its sole
               discretion (including without limitation Sites included in the
               Site Commitment that are paid for by the Base Rent and Monthly
               Reservation Fee and are not excess Sites), in an amount equal to
               the number of Sites for which there is any default, whether for
               failure to pay Excess Site Rent or otherwise;

               (ii) advance or otherwise pay any cost or expense to remedy a
               Lessee breach, in which event Lessee shall repay such amount to
               Lessor within ten (10) days after notice from Lessor (provided
               that Lessor shall first be required to provide in addition to the
               notices provided for in Section 14(a) and 14(b), five (5)
               business days notice to Lessee of Lessor's intent to undertake to
               remedy Lessee's breach), and/or

                                       15

               (iii) re-let the Leased Premises on such terms as Lessor
               reasonably deems appropriate, and in such event Lessee will
               remain liable for all Rent hereunder, less the net proceeds, if
               any, of any reletting by Lessor, after deducting all Lessor's
               expenses in connection with such reletting.

          (d)  Mutual Remedies. The defaulting party shall be liable for all
               expenses, including reasonable attorneys' fees and costs,
               incurred by a non-defaulting party in connection with any action
               to enforce the terms of this Lease, or in connection with any
               action for the recovery of the Leased Premises itself. If
               subsequent to the time period specified in Section 14(a) or 14(b)
               as applicable there continues to be an event of default, subject
               to the terms of Section 23, any suit or suits for the recovery of
               the amounts and damages owed hereunder may be brought by a
               non-defaulting party, from time to time, at such party's
               election, and nothing in this Lease will be deemed to require
               such party to await the date upon which this Lease or the term
               would have expired had there occurred no event of default.

          (e)  Additional Remedies. Upon the occurrence of any Lessee default
               that is not cured Lessor may, subject to the terms of Sections
               14(a) and (b) and Section 23: (i) enter upon the affected Site(s)
               without being liable for prosecution or any claims of damages of
               such entry, and do whatever Lessee is obligated to do under the
               terms of this Lease or any individual Site Schedule to correct
               the default, (ii) remove any or all of Lessee's equipment
               therefrom at the expense of Lessee, or (iii) disconnect Lessee's
               equipment. Notwithstanding the foregoing, if Lessor in its sole
               discretion determines there exists an emergency with respect to
               any Site, Lessor may enter upon the affected Site without being
               required to first provide Lessee any notice thereof or
               opportunity to cure. In such event, Lessor will provide Lessee
               notice thereof as soon as is reasonably practical under the
               circumstances. All costs in exercising such remedies (including
               the costs of any repairs required due to such removal) pursuant
               to this Section shall be at the expense of Lessee, which costs
               shall be reimbursed to Lessor upon receipt of an invoice(s).
               Lessee agrees to reimburse Lessor on demand for any expenses that
               Lessor may incur in effecting compliance with Lessee's
               obligations hereunder or any Site Schedule in this manner, and
               Lessee further agrees that Lessor shall not be liable for any
               damages resulting from such action (other than with respect to
               Lessor's gross negligence or willful misconduct). No action by
               Lessor pursuant to this Section shall be construed as an election
               on Lessor's part to terminate any individual Site Schedule,
               unless a written notice of such intention is given to Lessee, and
               Lessee's obligation to pay any sums payable hereunder shall not
               be terminated or suspended.

          (f)  Relocation Allowance and Reconciliation Offset. If Lessor fails
               to pay any undisputed part of the Relocation Allowance within the
               thirty (30) day period specified in Section 1(f), or any amount
               owed by Lessor pursuant to Section 13(c)(ii), and fails again to
               pay such amount within thirty (30) days after notice from Lessee
               indicating Lessee's intent to exercise its offset right
               hereunder, then Lessee may offset against the Rent otherwise
               payable hereunder the owed but unpaid undisputed portion of the
               Relocation Allowance or Section 13(c)(ii) reconciliation amount,
               as applicable.

     15.  CERTAIN REMEDIES: The remedies provided herein shall be cumulative and
          shall not preclude the assertion by any party hereto of any other
          rights or the seeking of any other remedies against the other parties
          hereto. Should a non-defaulting party permit a continuing default by a
          defaulting party under this Lease or any Site Schedule, the
          obligations of the defaulting party shall continue, and such
          permissive default shall not be construed as a renewal of the term
          hereof nor as a waiver of any of the rights of the non-defaulting
          party or obligations of the defaulting party hereunder. In addition to
          the other remedies in this Lease, and anything contained herein to the
          contrary notwithstanding, the non-defaulting party shall be entitled
          to specific performance or injunctive relief of any violation or
          attempted or threatened violation of this Lease by the defaulting
          party without the necessity to post a bond.

                                       16

     16.  REMOVAL OF LESSEE'S EQUIPMENT: After termination or expiration of this
          Lease, Lessee shall have thirty (30) days to remove its equipment, at
          Lessee's expense, and so long as Lessee's equipment remains on the
          applicable Site, Lessee shall pay Lessor a hold-over fee as specified
          in Section 2(b); provided, however, that if the month-to-month tenancy
          described in Section 2(b) is in effect after expiration, the thirty
          (30) day period for Lessee's removal of equipment shall not begin to
          run until the termination of such month-to-month tenancy. After the
          thirty (30) day period, Lessor shall have the right (but not the
          obligation) to disconnect and remove Lessee's equipment from said
          Site, and in such event Lessee shall pay Lessor upon demand 125% of
          the disconnection, removal and storage expenses incurred by or on
          behalf of Lessor.

     17.  SUBORDINATION: This Lease is and shall be subject and subordinate to
          all mortgages that may now or hereafter affect the Leased Premises and
          to all renewals, modifications, consolidations, replacements, and
          extensions thereof; provided, however, that so long as Lessee is not
          in default of any of its material obligations under this Lease,
          Lessee's quiet enjoyment thereunder shall not be disturbed by any
          purchaser of the applicable Leased Premises at foreclosure. This
          subordination shall be self-operative and no further instrument of
          subordination shall be required from Lessee. However, upon written
          request from Lessor, Lessee shall execute a certificate confirming
          such subordination.

     18.  LIENS: Lessee shall not suffer or permit any liens to stand against
          the Leased Premises, Sites or any part thereof by reason of any work,
          labor, service, or materials done for, or supplied for, or supplied to
          or claimed to have been done for, or supplied to, Lessee or anyone
          through or under Lessee ("Mechanics' Liens"). If any Mechanics' Lien
          shall at any time be filed against the Leased Premises or any Site,
          Lessee shall cause it to be discharged of record within thirty (30)
          days after the date Lessee receives notice from any party that the
          lien has been filed, by either payment, deposit, or bond. If Lessee
          fails to discharge any such Mechanics' Lien within such period, then,
          in addition to any other right or remedy of Lessor, Lessor may, but
          shall not be obligated to, procure the discharge of the Mechanics'
          Lien by either payment of the amount claimed, or deposit or bond. All
          amounts incurred by Lessor, including reasonable attorneys' fees, in
          procuring the discharge of such Mechanics' Lien, together with
          interest thereon at 10% per annum from the date of incurrence, shall
          become due and payable immediately by Lessee to Lessor.

     19.  ESTOPPEL CERTIFICATES: At any time, but not with less than fifteen
          (15) days prior notice, Lessee shall execute, acknowledge, and deliver
          to Lessor a statement in writing certifying that this Lease is
          unmodified and in full force and effect (or, if there have been any
          modifications, that the Lease is in full force and effect as modified
          and stating the modifications), the dates to which Rent and other
          charges, if any, have been paid in advance, and such other information
          as may be reasonably requested.

     20.  COMPLIANCE: Lessee agrees that Lessee will at all times comply with
          all applicable statutes, laws, ordinances, rules and judicial and
          administrative orders, whether now or hereafter existing, of all
          federal, state and local governmental authorities including without
          limitation those applicable to Lessee's equipment and the
          electromagnetic energy emitted from such equipment and including
          without limitation, regulations of the Federal Communications
          Commission, the Environmental Protection Agency, and the Occupational
          Safety and Health Administration. Lessor will not enforce against
          Lessee any governmental or legal compliance requirement with respect
          to a Site if Lessor does not uniformly enforce such requirement
          against all of the lessees at the subject location to the extent
          applicable to such lessees.

     21.  PRIME AGREEMENTS:

          (a)  Lessee acknowledges that Lessor's interest in and to any Site,
               and the access to such Site, may be subject to, or otherwise
               governed by, the terms and conditions of a third party lease,
               license, management or other similar agreement between a third
               party and Lessor (the "Prime Agreement"). Upon request by Lessee,
               Lessor will, to the extent not

                                       17

               restricted by an applicable confidentiality obligation, provide
               Lessee with copies of relevant portions of the subject Prime
               Agreements. Lessee hereby acknowledges that the terms,
               conditions, provisions, and obligations of this Lease and any
               Site Schedule, as they pertain to any Site affected by a Prime
               Agreement, shall be subject and subordinate to such Prime
               Agreement, and in the event of any conflict between the terms of
               such Prime Agreement and this Lease or any applicable Site
               Schedule, the terms of the Prime Agreement shall control. In the
               event of the termination of such Prime Agreement for any reason,
               the Site Schedules, pertaining to such Site(s) affected by the
               Prime Agreement shall automatically terminate, and Lessor shall
               use reasonable efforts to identify a suitable Replacement Site
               for the affected Site, and if no Replacement Site has been
               accepted by Lessee within fifteen (15) days after termination of
               the affected Site, and if the Removed Site Conditions are
               satisfied, then such affected Site(s) shall be deemed Removed
               Site(s).

          (b)  Lessee shall not knowingly do, attempt, permit or suffer anything
               to be done on a Site which results in a breach of a Prime
               Agreement, and at the written request of Lessee, Lessor will
               furnish Lessee with a summary of any restrictions (which summary
               may consist of redacted portions of the Prime Agreement)
               contained in said Prime Agreement ("Information") upon request,
               provided that (i) such Information is not confidential; and (ii)
               Lessee agrees that such Information shall be used for the sole
               purpose of enabling Lessee to perform its obligations regarding
               the Site. In performing its obligations under this Lease and each
               Site Schedule, Lessee will (A) limit dissemination of, and access
               to, the Information to Lessee's employees, agents or
               professionals who need to use the Information for the purpose of
               determining whether the Site is suitable for Lessee's purposes,
               (B) not disclose the Information to any third party, (C) not use
               the Information for any purpose other than the purposes allowed
               by this Section 21(b), and (D) take appropriate action, by
               instruction, agreement, or otherwise with any employees or agents
               of Lessee, such that Lessee fully performs its duties and
               obligations under this Section 21(b). In the event Lessor
               discloses Information to Lessee with respect to a Site for which
               Lessor paid Lessee a portion of the Relocation Allowance during
               the third year of the term hereof, Lessee covenants and warrants
               that for a period of one (1) year after expiration of the
               applicable Site Schedule, it will not enter into a lease,
               license, agreement or contract with such landlord/owner for

     23.  MEDIATION: Lessor and Lessee shall attempt to settle any claim or
          controversy arising out of this Lease or any Site Schedule through
          consultation and negotiation in the spirit of mutual friendship and
          cooperation. If such attempts fail, then the dispute shall first be
          submitted to a mutually-acceptable neutral mediator for mediation, for
          a period of at least thirty (30) days. If the parties cannot agree
          upon a mediator within five (5) days of best efforts, the parties will
          ask J.A.M.S./Endispute to appoint a mediator. Lessee shall remain
          obligated to pay all Rent during the pendency of any mediation
          hereunder, except if any dispute subject to mediation hereunder
          relates to the amount of Rent owed as a result of Removed Sites or
          Acquired Sites, then Lessee shall only be obligated to pay the Base
          Rent, the Monthly Reservation Fee, and Acquired Site Rent due under
          Section 13(c), plus if the Site Commitment is then met, the amount of
          Excess Site Rent determined by the Administrative Managers as of the
          date most recently preceding the date that written notice of a dispute
          and request for mediation is provided hereunder. Lessor will not
          interrupt or terminate service to any Site so long as, and to the
          extent that, all undisputed Rent as provided for in this Section 23 is
          timely paid to Lessor. If such amount is not timely paid, Lessor will
          have the right to terminate this Lease and exercise all other rights
          and remedies available to it hereunder or otherwise available in law
          or equity. The cost of mediation or any other alternate dispute
          resolution agreed upon by both parties shall be shared equally by
          Lessor and Lessee. Any dispute which cannot be so resolved between the
          parties within thirty (30) days of the date of the initial demand by
          either party for such mediation may, unless mutually agreed otherwise
          by the parties, be determined by a court of competent jurisdiction.
          The use of such a procedures shall not be construed to affect
          adversely the rights of either party under the doctrines of laches,
          waiver or estoppel. Nothing in this Section 23 shall prevent either
          party from resorting to judicial proceedings or to seek other remedies
          in a court of equity if (a) good faith efforts to resolve a dispute
          under these procedures have been unsuccessful, or (b) interim resort
          to a court is necessary to prevent serious and irreparable injury to a
          party or to others.

               stated herein. Any reference to a Rider, Exhibit, Schedule or

               hereof by this reference.

          (g)  Except as otherwise provided in the applicable Site Schedule,
               this Lease is solely for the benefit of the parties hereto, their
               successors and assigns permitted under this Lease and the
               indemnified parties hereunder and no provisions hereof shall be
               deemed to confer upon any other person any remedy, claim,

          (h)  Nothing contained herein shall be deemed or construed by the
               parties hereto or by any third person to create the relationship

               parties.

          (i)  If the approval or consent of any party is required under this
               Lease, such approval or consent may only be given in writing.

          (j)  Each of Lessee and Lessor and their respective affiliates that
               are parties hereto are jointly and severally liable and obligated
               under the terms of this Lease. If at anytime a party to a Site
               Schedule has not executed a counterpart of this Lease, such party
               will execute and deliver to the other parties a counterpart of
               this Lease, to evidence and confirm that it has joined into and
               become a party to this Lease, but no failure of any such Site
               Schedule party to do so will relieve any such party of its
               obligation hereunder by virtue of its entering into the subject
               Site Schedule.

          (k)  Lessor covenants and agrees that, upon Lessee's paying all
               required Rent and observing and performing all of the terms,
               covenants and conditions on Lessee's part to be observed and
               performed under this Lease (within applicable notice and grace
               periods), Lessee shall peacefully and quietly enjoy the Sites
               covered by each Site Schedule during the term hereof.

          (l)  At Lessee's request, Lessor agrees to execute a memorandum of
               agreement for a particular Site Schedule in a form mutually
               acceptable to the parties, so long as such recordation is not
               otherwise restricted or prohibited by the applicable Prime
               Agreement or other covenants affecting Lessor. Lessee agrees to
               provide Lessor with a copy of any such memorandum within five (5)
               business days following any recordation of such memorandum.

                                       26

IN WITNESS THEREOF, this Lease has been duly executed and delivered by Lessor
and Lessee on the date indicated below.

SECTION 2.2 INTEREST.

        (A) RATE OF INTEREST. The outstanding principal balance of each
Component of the Loan shall bear interest at a rate per annum equal to the
lesser of (i) the Component Rate, or following the Anticipated Repayment Date,
the ARD Component Rate, as applicable, for such Component and (ii) the Maximum
Rate.

        (B) DEFAULT RATE. Notwithstanding the foregoing, upon the occurrence and
during the continuance of an Event of Default and in any event from and after
the Maturity Date of the Loan and until the Loan and all other Obligations are
satisfied in full, the outstanding principal balance of each Component of the
Loan and all other Obligations shall bear interest until paid in full at a rate
per annum that is five percent (5.0%) in excess of the then applicable Component
Rate, or the then applicable ARD Component Rate, for each Component otherwise
applicable under this Loan Agreement and the Note (the "DEFAULT RATE").

        (C) COMPUTATION OF INTEREST. Interest on the Loan and all other
Obligations owing to Lender shall be computed on the basis of a 360-day year
consisting of twelve (12) thirty (30) day months, and shall be charged for the
actual number of days elapsed during any partial month. Interest shall be
payable in arrears (except with respect to the number of days from the Payment
Date in any Interest Accrual Period to the last day of such Interest Accrual
Period as to which interest shall be payable in advance, if any).

        (D) INTEREST LAWS. Notwithstanding any provision to the contrary
contained in this Loan Agreement or the other Loan Documents, the Borrowers
shall not be required to pay, and

                                       22

Lender shall not be permitted to collect, any amount of interest in excess of
the maximum amount of interest permitted by law ("EXCESS INTEREST"). If any
Excess Interest is provided for or determined by a court of competent
jurisdiction to have been provided for in this Loan Agreement or in any of the
other Loan Documents, then in such event: (1) the provisions of this subsection
shall govern and control; (2) the Borrowers shall not be obligated to pay any
Excess Interest; (3) any Excess Interest that Lender may have received hereunder
shall be, at Lender's option, (a) applied as a credit against either or both of
the outstanding principal balance of the Loan or accrued and unpaid interest
thereunder (not to exceed the maximum amount permitted by law), (b) refunded to
the payor thereof, or (c) any combination of the foregoing; (4) the interest
rate(s) provided for herein shall be automatically reduced to the maximum lawful
rate allowed from time to time under applicable law (the "MAXIMUM RATE"), and
this Loan Agreement and the other Loan Documents shall be deemed to have been
and shall be, reformed and modified to reflect such reduction; and (5) the
Borrowers shall not have any action against Lender for any damages arising out
of the payment or collection of any Excess Interest. Notwithstanding the
foregoing, if for any period of time interest on any Obligation is calculated at
the Maximum Rate rather than the applicable rate under this Loan Agreement, and
thereafter such applicable rate becomes less than the Maximum Rate, the rate of
interest payable on such Obligations shall, to the extent permitted by law,
remain at the Maximum Rate until Lender shall have received or accrued the
amount of interest which Lender would have received or accrued during such
period on Obligations had the rate of interest not been limited to the Maximum
Rate during such period. If the Default Rate shall be finally determined to be
unlawful, then the Component Rate, or the ARD Component Rate, as applicable,
with respect to each Component shall be applicable during any time when the
Default Rate would have been applicable hereunder, provided however that if the
Maximum Rate is greater or lesser than the Component Rate, or the ARD Component
Rate, as applicable, with respect to any Component, then the foregoing
provisions of this paragraph shall apply.

        (E) LATE CHARGES. If an Event of Default regarding non-payment of
principal, interest or other sums due hereunder or under any of the other Loan
Documents shall occur, then the Borrowers shall pay to Lender, in addition to
all sums otherwise due and payable, a late fee in an amount equal to five
percent (5.0%) of such principal, interest or other sums due hereunder or under
any other Loan Document, such late charge to be immediately due and payable
without demand by Lender.

                                       23

SECTION 2.3 ADDITIONAL BORROWERS. With Lender's approval (in its sole
discretion), on or before February 5, 2004, PTI may elect to cause one or more
of its Affiliates to assume and become jointly and severally obligated under the
Note and the Loan Documents for repayment of the Loan, including subjecting one
or more properties owned by such Affiliate to be added as Collateral for
repayment of the Loan. Upon such election, (i) Schedule I shall be amended to
add such additional Affiliates as are designated to become "Borrowers"
hereunder; (ii) all references to the Borrowers hereunder shall include all of
the Borrowers identified on such amended Schedule I; and (iii) each additional
designated Affiliate shall execute an assumption and joinder agreement in the
form of EXHIBIT E.

SECTION 2.4 PAYMENTS.

        (A) PAYMENTS OF INTEREST AND PRINCIPAL. The Borrowers shall make
payments of interest and principal on the Note as follows:

                 (i) On each Payment Date commencing with the Payment Date in
March 2004, and on each Payment Date thereafter through and including the
Anticipated Repayment Date, the Borrowers shall make a payment of interest at
the applicable Component Rate on each Component for the Interest Accrual Period
immediately preceding each such Payment Date (together with any late charges,
Servicing Fees and other expenses then due and owing under the Loan Documents),
and in addition shall make a payment of principal on the Loan in an amount equal
to the Scheduled Principal Payment which shall be applied first to pay late
charges, the charges and expenses of Lender, and any Servicing Fees as provided
hereunder, second to currently accruing interest at the applicable Component
Rate on each Component, and third, to the Principal Amount of Component A until
the Principal Amount of Component A has been reduced to zero, and then
sequentially to each Component with an earlier alphabetical designation (i.e., B
through G, in that order until the Principal Amount of each Component is repaid
in full; and

                 (ii) On each Payment Date, commencing with the first Payment
Date following the Anticipated Repayment Date, and on each Payment Date
thereafter through the Maturity Date, interest shall accrue on each Component at
the applicable ARD Component Rate. Commencing on the first Payment Date after
the Anticipated Repayment Date, and on each Payment Date thereafter through the
Maturity Date, 100% of Excess Cash Flow for the calendar month preceding the
calendar month in which such Payment Date occurs shall be due and shall be
applied, first to pay late charges, the charges and expenses of Lender, and
Servicing Fees as provided hereunder, second to currently accruing interest at
the applicable Component Rate on each Component, third, to the Principal Amount
of Component A until the Principal Amount of Component A has been reduced to
zero, and then sequentially to each Component with an earlier alphabetical
designation (i.e., B through G, in that order) until the Principal Amount of
each Component is repaid in full, and fourth, to the Accrued Interest on
Component A until the Accrued Interest with respect to Component A has been
reduced to zero, and then sequentially to each Component with an earlier
alphabetical designation (i.e., B through G, in that order until the Accrued
Interest with respect to each such Component is paid in full. Until paid, the
excess of (x) the applicable ARD Component Rate for each Component over (y) the
applicable Component Rate for each Component, shall be deferred and, on each
Payment Date, shall be added to any

                                       24

interest previously deferred pursuant to this sentence and remaining unpaid (the
"ACCRUED INTEREST"). Accrued Interest shall not bear interest.

        (B) DATE AND TIME OF PAYMENT. Two (2) Business Days prior to the
applicable Payment Date, Lender shall provide a statement of principal and
interest required to be paid on such Payment Date. The Borrowers shall receive
credit for payments on the Loan which are transferred to the account of Lender
as provided below (i) on the day that such funds are received by Lender if such
receipt occurs by 2:00 p.m. (New York time) on such day, or (ii) on the next
succeeding Business Day after such funds are received by Lender if such receipt
occurs after 2:00 p.m. (New York time). Whenever any payment to be made
hereunder shall be stated to be due on a day that is not a Business Day, the
payment may be made on the next succeeding Business Day.

        (C) MANNER OF PAYMENT; APPLICATION OF PAYMENTS. The Borrowers promise to
pay all of the Obligations relating to the Loan as such amounts become due or
are declared due pursuant to the terms of this Loan Agreement. All payments by
the Borrowers on the Loan shall be made without deduction, defense, set off or
counterclaim and in immediately available funds delivered to Lender by wire
transfer to such accounts at such banks as Lender may from time to time
designate. Prior to an Event of Default, each payment shall be applied in
accordance with Section 2.4(A) hereof and, to the extent sufficient funds are
contained in the Lock Box Account, or an Account or Sub-Account thereof, to make
the required monthly payments to the applicable Reserves and Sub-Accounts on
such Payment Date, the Borrowers shall be deemed to have satisfied its
obligation to make such payments. Upon the occurrence and during the continuance
of an Event of Default, payments shall be applied to the Obligations in such
order as Lender shall determine in its sole and absolute discretion.

SECTION 2.5 MATURITY.

        (A) MATURITY DATE. To the extent not sooner due and payable in
accordance with the Loan Documents, the then outstanding principal balance of
the Loan, all accrued and unpaid interest thereon (and including interest
through the end of the Interest Accrual Period then in effect), and all other
sums then owing to Lender hereunder and under the Note, the Deeds of Trust and
the other Loan Documents, shall be due and payable on the Maturity Date.

SECTION 2.6 PREPAYMENT.

        (A) LIMITATION ON PREPAYMENT. The Borrowers shall have no right to
prepay the Loan in whole or in part, except as expressly set forth in this Loan
Agreement. (i) From and after the second (2nd) anniversary of the Closing Date,
the Borrowers may prepay the Loan in whole, or in part, at any time, and (ii) if
a partial prepayment is required to be made to cure a Default under Sections
8.1(E), 8.1(P) or 8.1(Q), the Borrower may prepay the Loan in part, at any time,
provided that (x) the Borrowers shall provide to Lender not less than fifteen
(15) days' prior written notice of such prepayment, (y) together with such
prepayment the Borrowers also shall pay all accrued and unpaid interest and all
other Obligations then due and owing, and (z) if such prepayment occurs on any
day other than a Payment Date, then together therewith the Borrowers also shall
pay to Lender the amount of interest that would have accrued on the amount being
prepaid from and including the date of such prepayment to the end of such
Interest Accrual

                                       25

Period. Subject to the provisions of Section 2.4(C), all prepayments made under
this Loan Agreement shall be applied in accordance with Section 2.4(A).

        (B) YIELD MAINTENANCE DUE. If any prepayment of all or any portion of
the Loan shall occur (including on account of acceleration of the Loan (whether
or not due to an Event of Default) or otherwise), then except only as expressly
provided in this Loan Agreement or the other Loan Documents to the contrary, the
Borrowers shall pay the Yield Maintenance on the amount prepaid to Lender
together with such prepayment, as liquidated damages and compensation for costs
incurred, and in addition to all other amounts due and owing to Lender.
Notwithstanding the foregoing, no Yield Maintenance will be due as to a
prepayment of the Loan on any Payment Date that occurs during or after the three
(3) month period immediately preceding the Anticipated Repayment Date (provided
the amount of interest that would have accrued on the amount being prepaid from
and including the date of such prepayment through the following Payment Date
shall be payable with such prepayment). The foregoing designation of any amount
of Yield Maintenance in this Agreement shall not create a right to prepay at any
time or in any circumstances where this Loan Agreement does not expressly state
that such a right exists. "YIELD MAINTENANCE" means the excess, if any, of (x)
the present value on the date of prepayment (by acceleration or otherwise) of
all future installments of principal and interest which the Borrowers would
otherwise be required to pay on that portion of the applicable Component prepaid
from the date of such prepayment to and including the Payment Date that is three
(3) months prior to the Anticipated Repayment Date absent such prepayment,
assuming the entire unpaid Principal Amount of such Component is required to be
paid on such Payment Date, with such present value being determined by the use
of a discount rate equal to the sum of (a) the yield to maturity (adjusted to a
"mortgage equivalent basis" pursuant to the standards and practices of the
Securities Industry Association), on the date of such prepayment of the United
States Treasury Security having the term to maturity closest to the Payment Date
that is three (3) months prior to the Anticipated Repayment Date, and (b) .50%,
over (y) that portion of the applicable Component prepaid on the date of such
prepayment.

SECTION 2.7 OUTSTANDING BALANCE. The balance on Lender's books and records shall
be presumptive evidence (absent manifest error) of the amounts owing to Lender
by the Borrowers; provided that any failure to record any transaction affecting
such balance or any error in so recording shall not limit or otherwise affect
the Borrowers' obligation to pay the Obligations.

SECTION 2.8 TAXES. Any and all payments or reimbursements made hereunder or
under the Note shall be made free and clear of and without deduction for any and
all taxes, withholding taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto arising out of or in
connection with the transactions contemplated by the Loan Documents (all such
taxes, levies, imposts, deductions, charges or withholdings and all liabilities
with respect thereto (excluding taxes imposed on net income in accordance with
the following sentence) herein "TAX LIABILITIES"). Notwithstanding the
foregoing, the Borrowers shall not be liable for taxes imposed on the net income
of Lender by the jurisdiction under the laws of which Lender is organized or
doing business or any political subdivision thereof and taxes imposed on its net
income by the jurisdiction of Lender's applicable lending office or any
political subdivision thereof. If the Borrowers shall be required by law to
deduct any such Tax Liabilities (or amounts in estimation or reimbursement for
the same) from or in respect of any sum payable hereunder to Lender, then the
sum payable hereunder shall be increased as may be necessary so that, after

                                       26

making all required deductions, Lender receives an amount equal to the sum it
would have received had no such deductions been made.

SECTION 2.9 REASONABLENESS OF CHARGES. The Borrower Parties agree that (i) the
actual costs and damages that Lender would suffer by reason of an Event of
Default (exclusive of the attorneys' fees and other costs incurred in connection
with enforcement of Lender's rights under the Loan Documents) or a prepayment
would be difficult and needlessly expensive to calculate and establish, and (ii)
the amounts of the Default Rate, the late charges, and the Yield Maintenance are
reasonable, taking into consideration the circumstances known to the parties at
this time, and (iii) such Default Rate and late charges and Lender's reasonable
attorneys' fees and other costs and expenses incurred in connection with
enforcement of Lender's rights under the Loan Documents shall be due and payable
as provided herein, and (iv) such interest at the Default Rate, late charges,
Yield Maintenance, and the obligation to pay Lender's reasonable attorneys' fees
and other enforcement costs do not, individually or collectively, constitute a
penalty.

SECTION 2.10 SERVICING/SPECIAL SERVICING. Lender may change the Servicer from
time to time without the consent of the Borrowers, on prior written notice to
the Borrowers. The Borrowers expressly acknowledge and agree that the Servicer's
fees, and if the Loan becomes a specially serviced loan, any additional fees of
the Servicer payable in connection therewith, and such additional trust fund
expenses and fees, including any Rating Agency fees, as shall be incurred in
connection with the Securitization (collectively, the "SERVICING FEE") shall be
payable by the Borrowers and shall constitute a portion of the Obligations;
provided, however, that at no time shall the Borrowers be liable for Servicing
Fees in excess of those fees charged to Lender. Lender shall provide a
reasonably detailed statement of Servicing Fees for which the Borrowers are
liable two (2) Business Days prior to the date when due; provided that failure
to timely provide such statement shall not relieve the Borrowers from the
obligation to pay all such Servicing Fees.

                                   ARTICLE III

Trust in such states and such other matters as Lender may reasonably request;
(b) opinions of Richards, Layton & Finger or other Delaware legal counsel,
acceptable to Lender, for each of the Guarantor and Manager that, among other

voluntary bankruptcy filing by the Guarantor or Manager, (x) such unanimous

        (F) TITLE POLICIES. On or before the Closing Date, Lender shall have

SECTION 4.1 ORGANIZATION, POWERS, CAPITALIZATION, GOOD STANDING, BUSINESS.

        (A) ORGANIZATION AND POWERS. Each Borrower Party is duly organized,

operate its properties, to carry on its business as

                                       30

now conducted and proposed to be conducted, and to enter into each Loan Document
to which it is a party and to perform the terms thereof.

        (B) QUALIFICATION. Each Borrower Party is duly qualified and in good
standing in the state of its formation. In addition, each Borrower Party is duly
qualified and in good standing in each state where necessary to carry on its
present business and operations, except in jurisdictions in which the failure to

Material Adverse Effect.

        (C) ORGANIZATION. The organizational chart set forth as SCHEDULE 4.1(C)
accurately sets forth the direct and indirect ownership structure of the
Borrowers.

SECTION 4.2 AUTHORIZATION OF BORROWING, ETC.

        (A) AUTHORIZATION OF BORROWING. The Borrowers have the power and
authority to incur the Indebtedness evidenced by the Note. The execution,
delivery and performance by each Borrower Party of each of the Loan Documents to
which it is a party and the consummation of the transactions contemplated
thereby have been duly authorized by all necessary limited liability company,
partnership, trustee, corporate or other action, as the case may be.

        (B) NO CONFLICT. The execution, delivery and performance by each
Borrower Party of the Loan Documents to which it is a party and the consummation
of the transactions contemplated thereby do not and will not: (1) violate (x)
any provision of law applicable to any Borrower Party; (y) the partnership
agreement, certificate of limited partnership, certificate of formation,
certificate of incorporation, bylaws, declaration of trust, limited liability
company agreement, operating agreement or other organizational documents, as the
case may be, of each Borrower Party; or (z) any order, judgment or decree of any
Governmental Authority binding on any Borrower Party or any of its Affiliates;
(2) conflict with, result in a breach of or constitute (with due notice or lapse
of time or both) a default under any Contractual Obligation of any Borrower
Party or any of its Affiliates (except where such breach will not cause a
Material Adverse Effect); (3) result in or require the creation or imposition of
any material Lien (other than the Lien of the Loan Documents) upon the
Properties or assets of any Borrower Party; or (4) require any approval or
consent of any Person under any Contractual Obligation of any Borrower Party,
which approvals or consents have not been obtained on or before the dates
required under such Contractual Obligation, but in no event later than the
Closing Date (except where the failure to obtain such approval or consent will
not have a Material Adverse Effect).

        (C) GOVERNMENTAL CONSENTS. The execution and delivery by each Borrower
Party of the Loan Documents to which it is a party, and the consummation of the
transactions contemplated thereby do not and will not require any registration
with, consent or approval of, or notice to, or other action to, with or by, any
Governmental Authority.

        (D) BINDING OBLIGATIONS. This Loan Agreement is, and the Loan Documents,
including the Note, when executed and delivered will be, the legally valid and
binding obligations of each Borrower Party that is a party thereto, enforceable
against each of the Borrower Parties, as applicable, in accordance with their
respective terms, subject to bankruptcy, insolvency, moratorium, reorganization
and other similar laws affecting creditor's rights. No

                                       31

Borrower Party has any defense or offset to any of its obligations under the
Loan Documents to which it is a party. No Borrower Party has any claim against
Lender or any Affiliate of Lender.

SECTION 4.3 FINANCIAL STATEMENTS. All financial statements concerning any of the
Borrowers and their Affiliates which have been furnished by or on behalf of the
Borrowers to Lender pursuant to this Loan Agreement present fairly in all
material respects the financial condition of the Persons covered thereby.

SECTION 4.4 INDEBTEDNESS AND CONTINGENT OBLIGATIONS. As of the Closing, the
Borrowers shall have no outstanding Indebtedness or Contingent Obligations other
than the Obligations or any other Permitted Indebtedness.

SECTION 4.5 TITLE TO THE PROPERTIES. The Borrowers have good and marketable fee
simple title (or, in the case of the Ground Leased Properties, leasehold title)
to the Properties, other than the Managed Properties, free and clear of all
Liens except for the Permitted Encumbrances. The Borrowers own and will own at
all times all personal property on the Properties (other than the Managed
Properties and personal property which is either owned by tenants of such
Property, not used or necessary for the operation of the applicable Property, or
leased by the Borrowers as permitted hereunder), subject only to the Permitted
Encumbrances. The Deeds of Trust will create (i) a valid, perfected first lien
on the applicable Properties, subject only to the Permitted Encumbrances, and
(ii) perfected first priority security interests in and to, and perfected
collateral assignments of, all personalty in connection therewith (including the
Rents and the Leases), all in accordance with the terms thereof, in each case
subject only to any applicable Permitted Encumbrances. Except as set forth on
SCHEDULE 4.5, there are no proceedings in condemnation or eminent domain
affecting any of the Properties, and to the actual Knowledge of the Borrowers,
none is threatened. No Person has any option or other right to purchase all or
any portion of any of the Properties owned by the Borrowers or any interest
therein. There are no mechanic's, materialman's or other similar liens or claims
which have been filed for work, labor or materials affecting the Properties
which are or will be liens prior to, or equal or coordinate with, the lien of
the applicable Deed of Trust the effect of which is reasonably likely to have a
Material Adverse Effect. The Permitted Encumbrances, in the aggregate, do not
materially interfere with the benefits of the security intended to be provided
by the Deeds of Trust and this Loan Agreement, materially and adversely affect
the value of any of the Mortgaged Properties taken as a whole, impair the use or
operations of the Mortgaged Properties or impair the Borrowers' ability to pay
their respective obligations in a timely manner.

SECTION 4.6 ZONING; COMPLIANCE WITH LAWS. The Properties and the use thereof
comply with all applicable zoning, subdivision and land use laws, regulations
and ordinances, all applicable health, fire, building codes, parking laws and
all other laws, statutes, codes, ordinances, rules and regulations applicable to
the Properties, or any of them, including without limitation the Americans with
Disabilities Act, except to the extent failure to so comply would not, in the
aggregate, be reasonably likely to have a Material Adverse Effect. All permits,
licenses and certificates for the lawful use, occupancy and operation of each
component of each of the Properties given as Collateral hereunder in the manner
in which it is currently being used, occupied and operated have been obtained
and are current and in full force and effect, except to the extent failure to
obtain any such permits, licenses or certificates would not, in the aggregate,
be reasonably likely to have a Material Adverse Effect. To the Borrowers'
Knowledge,

                                       32

(i) except as set forth on SCHEDULE 4.6, no legal proceedings are pending or
threatened with respect to the zoning of any Property and (ii) except as set
forth in the Title Policies, neither the zoning nor any other right to
construct, use or operate any Property is in any way dependent upon or related
to any real estate other than such Property.

SECTION 4.7 LEASES; AGREEMENTS.

        (A) LEASES; AGREEMENTS. The Borrowers have delivered to Lender true and
complete copies (in all material respects) of all (i) Leases and (ii) Material
Agreements affecting the operation and management of the Properties, and such
Leases and Material Agreements have not been modified or amended except pursuant
to amendments or modifications delivered to Lender. Except for the rights of the
Manager pursuant to the existing Management Agreement, and the fee owners of
Managed Properties, no Person has any right or obligation to manage any of the
Properties or to receive compensation in connection with such management. Except
for the parties to any leasing brokerage agreement that has been delivered to
Lender, no Person has any right or obligation to lease or solicit tenants for
the Properties, or (except for cooperating outside brokers) to receive
compensation in connection with such leasing.

        (B) RENT ROLL, DISCLOSURE. A true and correct copy of the Rent Roll has
been delivered to Lender. Except only as specified in the Rent Roll, or as
otherwise disclosed to Lender in the estoppel certificates delivered to Lender
at Closing, to the Borrowers' Knowledge, (i) the Leases are in full force and
effect; (ii) the Borrowers have not given any notice of default to any tenant
under any Lease which remains uncured; (iii) no tenant has any set off, claim or
defense to the enforcement of any Lease; (iv) no tenant is in arrears in the
payment of rent, additional rent or any other charges whatsoever due under any
Lease, or is materially in default in the performance of any other obligations
under such Lease; and (v) there are no rent concessions (whether in form of cash
contributions, work agreements, assumption of an existing tenant's other
obligations, or otherwise) or extensions of time whatsoever not reflected in
such Rent Roll, except to the extent that the failure of the representations set
forth in items (i) through (iv) to be true with respect to Leases (other than
Material Leases) is not reasonably likely to have a Material Adverse Effect. To
the Borrowers' Knowledge, each of the Leases is valid and binding on the parties
thereto in accordance with its terms.

        (C) MANAGEMENT AGREEMENT. The Borrowers have delivered to Lender a true
and complete copy of the Management Agreement to which they are a party that
will be in effect on the Closing Date, and such Management Agreement has not
been modified or amended except pursuant to amendments or modifications
delivered to Lender. The Management Agreement is in full force and effect and no
default by any of the Borrowers or Manager exists thereunder.

SECTION 4.8 CONDITION OF THE PROPERTIES. Except as set forth on SCHEDULE 4.8,
all Improvements are in good repair and condition. Any damage to the
Improvements identified on SCHEDULE 4.8 are fully covered by insurance (subject
to the applicable deductible) and the required repairs identified thereon are
capable of being completed within six (6) months of the Closing Date. The
Borrowers are not aware of any latent or patent structural or other material
defect or deficiency in the Properties and all necessary utilities are fully
connected to the Improvements and are fully operational, are sufficient to meet
the reasonable needs of each of the Properties as now used or presently
contemplated to be used, and no other utility facilities or

                                       33

repairs are necessary to meet the reasonable needs of each of the Properties as
now used or presently contemplated. To the Borrowers' Knowledge, none of the
Improvements create encroachments over, across or upon the Properties' boundary
lines, rights of way or easements, and no building or other improvements on
adjoining land create such an encroachment, which could reasonably be expected
to have a Material Adverse Effect. Access has been insured by the Title Company
for all Core Mortgaged Properties that are also Ground Leased Properties and the
Borrowers have access to each of the Core Mortgaged Properties that are not
Ground Leased Properties except to the extent that failure to have such access
would not be reasonably likely to have a Material Adverse Effect.

SECTION 4.9 LITIGATION; ADVERSE FACTS. Except as set forth on SCHEDULE 4.9,
there are no judgments outstanding against any Borrower Party, or affecting any
of the Properties or any property of any Borrower, nor to the Borrower's
Knowledge after due inquiry is there any action, charge, claim, demand, suit,
proceeding, petition, governmental investigation or arbitration now pending or
threatened against any Borrower Party or any of the Properties that could
reasonably be expected to result in a Material Adverse Effect.

SECTION 4.10 PAYMENT OF TAXES. All federal, state and local tax returns and
reports of each Borrower required to be filed have been timely filed (or each
Borrower has timely filed for an extension and the applicable extension has not
expired), and all taxes, assessments, fees and other governmental charges
(including any payments in lieu of taxes) upon such Person and upon its
properties, assets, income and franchises which are due and payable have been
paid except to the extent same are being contested in accordance with Section
5.3(B).

SECTION 4.11 ADVERSE CONTRACTS. Except for the Loan Documents, the Borrowers are
not parties to or bound by, nor is any property of such Person subject to or
bound by, any contract or other agreement which restricts such Person's ability
to conduct its business in the ordinary course as currently conducted that,
either individually or in the aggregate, has a Material Adverse Effect or could
reasonably be expected to have a Material Adverse Effect.

SECTION 4.12 PERFORMANCE OF AGREEMENTS. To the Borrowers' Knowledge, no Borrower
is in default in the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in any Contractual Obligation of
any such Borrower which could reasonably be expected to have a Material Adverse
Effect, and no condition exists that, with the giving of notice or the lapse of
time or both, would constitute such a default which could reasonably be expected
to have a Material Adverse Effect.

SECTION 4.13 GOVERNMENTAL REGULATION. No Borrower Party is subject to regulation
under the Public Utility Holding Company Act of 1935, the Federal Power Act or
the Investment Company Act of 1940 or to any federal or state statute or
regulation limiting its ability to incur indebtedness for borrowed money.

SECTION 4.14 EMPLOYEE BENEFIT PLANS. Except as set forth on SCHEDULE 4.14, no
Borrower Party maintains or contributes to, or has any obligation (including a
contingent obligation) under, any Employee Benefit Plans.

                                       34

SECTION 4.15 BROKER'S FEES. No broker's or finder's fee, commission or similar
compensation will be payable by or pursuant to any contract or other obligation
of the Borrowers with respect to the making of the Loan or any of the other
transactions contemplated hereby or by any of the Loan Documents. The Borrowers
shall indemnify, defend, protect, pay and hold Lender harmless from any and all
broker's or finder's fees claimed to be due in connection with the making of the
Loan arising from any Borrower Parties' actions.

SECTION 4.16 SOLVENCY. The Borrowers (a) have not entered into the transaction
or any Loan Document with the actual intent to hinder, delay, or defraud any
creditor and (b) received reasonably equivalent value in exchange for its
obligations under the Loan Documents. Giving effect to the Loan, the fair
saleable value of each Borrower's assets exceed and will, immediately following
the making of the Loan, exceed such Borrower's total liabilities, including,
without limitation, subordinated, unliquidated, disputed and Contingent
Obligations. The fair saleable value of each Borrower's assets is and will,
immediately following the making of the Loan, be greater than the Borrower's
probable liabilities, including the maximum amount of its Contingent Obligations
on its debts as such debts become absolute and matured. Each Borrower's assets
do not and, immediately following the making of the Loan will not, constitute
unreasonably small capital to carry out its business as conducted or as proposed
to be conducted. The Borrowers do not intend to, and do not believe that they
will, incur Indebtedness and liabilities (including Contingent Obligations and
other commitments) beyond its ability to pay such Indebtedness and liabilities
as they mature (taking into account the timing and amounts of cash to be
received by the Borrowers and the amounts to be payable on or in respect of
obligations of the Borrowers).

SECTION 4.17 DISCLOSURE. No financial statements or other information furnished
to Lender by or on behalf of any of the Borrowers contains any untrue
representation, warranty or statement of a material fact, or omits to state a
material fact necessary in order to make the statements contained therein not
misleading. No Loan Document or any other document, certificate or written
statement for use in connection with the Loan and prepared by the Borrowers, or
any information provided by any Borrower and contained in, or used in
preparation of, any document or certificate for use in connection with the Loan,
contains any untrue representation, warranty or statement of a material fact, or
omits to state a material fact necessary in order to make the statements
contained therein not misleading. There is no fact known to the Borrowers that
has had or will have a Material Adverse Effect and that has not been disclosed
in writing to Lender by the Borrowers.

SECTION 4.18 USE OF PROCEEDS AND MARGIN SECURITY. The Borrowers shall use the
proceeds of the Loan only for the purposes set forth herein and consistent with
all applicable laws, statutes, rules and regulations. No portion of the proceeds
of the Loan shall be used by the Borrowers or any Person in any manner that
might cause the borrowing or the application of such proceeds to violate
Regulation T, Regulation U or Regulation X or any other regulation of the Board
of Governors of the Federal Reserve System.

SECTION 4.19 INSURANCE. Set forth on SCHEDULE 4.19 is a complete and accurate
description of all policies of insurance for each Borrower that are in effect as
of the Closing Date. Such insurance policies conform to the requirements of
Section 5.4. No notice of cancellation has

                                       35

been received with respect to such policies, and, to each Borrower's Knowledge,
the Borrowers are in compliance with all conditions contained in such policies.

SECTION 4.20 INVESTMENTS. The Borrowers have no (i) direct or indirect interest
in, including without limitation stock, partnership interest or other securities
of, any other Person (other than the other Borrowers), or (ii) direct or
indirect loan, advance or capital contribution to any other Person, including
all indebtedness and accounts receivable from that other Person (other than the
other Borrowers).

benefit plan as defined in Section 3(3) of ERISA which is subject to ERISA, (ii)
a plan as defined in Section 4975(e)(1) of the IRC which is subject to Section
4975 of the IRC, or (iii) an entity whose underlying assets constitute "plan
assets" of any such employee benefit plan or plan for purposes of Title I of
ERISA of Section 4975 of the IRC; provided that, in making such representation,
the Borrowers have assumed that (i) no portion of the Loan shall be funded with
plan assets of any employee benefit plan that is subject to Title I of ERISA or
any plan that is covered by Section 4975 of the Code unless the Lender is
eligible to apply one or more exemptions such that the Loan will not constitute
a nonexempt prohibited transaction under Section 406 of ERISA or that could
subject a Borrower Party or its Affiliates to an excise tax under Section 4975
of the IRC; and (ii) such assumption in the preceding clause is true and correct
with respect to any party to which Lender transfers or assigns any portion of
the Loan.

SECTION 4.22 GOVERNMENTAL PLAN. No Borrower Party is or will be a "governmental
plan" within the meaning of Section 3(32) of ERISA and transactions by or with
the Borrowers are not and will not be subject to state statutes applicable to
the Borrowers' regulating investments of and fiduciary obligations with
obligations with respect to governmental plans.

such changes as are necessary to comply with the reasonable requirements of
Lender. If any such budget (or amendment thereto) requiring Lender's approval is
not approved or deemed approved prior to the period covered thereby, the
applicable budget in effect shall remain in effect until the budget (or
amendment thereto) is approved or deemed approved. Lender's consent to any
budget or amendments thereto shall be deemed given, if the first correspondence
from the Borrowers to Lender requesting such approval is in an envelope marked
"PRIORITY" and contains a bold-faced, conspicuous legend at the top of the first
page thereof stating that "IF YOU FAIL TO RESPOND TO OR TO EXPRESSLY DENY THIS
REQUEST FOR APPROVAL IN WRITING WITHIN TEN (10) DAYS, YOUR APPROVAL MAY BE
DEEMED GIVEN", and is accompanied by the information and documents required
above and any other information reasonably requested by Lender in writing prior
to the expiration of such ten (10) day period in order to adequately review the
same has been delivered and, if Lender fails to respond or to expressly deny
such request for approval in writing within the ten (10) day period, a second
notice is delivered to Lender from the Borrowers in an envelope marked
"PRIORITY" requesting approval containing a bold-faced, conspicuous legend at
the top of the first page thereof stating that "IF YOU FAIL TO RESPOND TO OR
EXPRESSLY DENY THIS REQUEST FOR APPROVAL IN WRITING WITHIN TEN (10) DAYS, YOUR
APPROVAL SHALL BE DEEMED GIVEN" and Lender fails to respond or to expressly deny
each request for approval within the ten (10) day period.

        (E) MATERIAL NOTICES.

                 (i) The Borrowers shall promptly deliver, or cause to be
delivered, copies of all notices given or received with respect to a default
under any term or condition related to any Permitted Indebtedness of any
Borrower, and shall notify Lender within five (5) Business Days of any potential
or actual event of default with respect to any such Permitted Indebtedness.

                 (ii) The Borrowers shall promptly deliver to Lender copies of
any and all material notices (including without limitation any notice alleging
any default or breach which is reasonably expected to result in a termination)
received with respect to any Material Agreement or any Material Lease.

        (F) EVENTS OF DEFAULT, ETC. Promptly upon any of the Borrowers obtaining
knowledge of any of the following events or conditions, such Borrower shall
deliver a certificate executed on its behalf by its chief financial officer or
similar officer specifying the nature and

                                       42

period of existence of such condition or event and what action such Borrower or
any Affiliate thereof has taken, is taking and proposes to take with respect
thereto: (i) any condition or event that constitutes an Event of Default; (ii)
any Material Adverse Effect; or (iii) any actual or alleged breach or default or
assertion of (or written threat to assert) remedies under the Management
Agreement, any Ground Lease or any Easement.

        (G) LITIGATION. Promptly upon any of the Borrowers obtaining knowledge
of (1) the institution of any action, suit, proceeding, governmental
investigation or arbitration against the Borrowers or any of the Properties not
previously disclosed in writing by the Borrowers to Lender which would be
reasonably likely to have a Material Adverse Effect or is not covered by
insurance or (2) any material development in any action, suit, proceeding,
governmental investigation or arbitration at any time pending against or
affecting the Borrowers or the Properties which, in each case, if adversely
determined could reasonably be expected to have a Material Adverse Effect, the
Borrowers will give notice thereof to Lender and, upon request from Lender,
provide such other information as may be reasonably available to them to enable
Lender and its counsel to evaluate such matter.

        (H) INSURANCE. Prior to the end of each insurance policy period of the
Borrowers, the Borrowers will deliver certificates, reports, and/or other
information (all in form and substance reasonably satisfactory to Lender), (i)
outlining all material insurance coverage maintained as of the date thereof by
the Borrowers and all material insurance coverage planned to be maintained by
the Borrowers in the subsequent insurance policy period and (ii) evidencing
payment in full of the premiums for such insurance policies.

        (I) OTHER INFORMATION. With reasonable promptness, Borrowers will
deliver such other information and data with respect to such Person and its
Affiliates or the Properties as from time to time may be reasonably requested by
Lender.

SECTION 5.2 EXISTENCE; QUALIFICATION. The Borrowers will at all times preserve
and keep in full force and effect their existence as a limited partnership,
limited liability company, or corporation, as the case may be, and all rights
and franchises material to its business, including their qualification to do
business in each state where it is required by law to so qualify. Without
limitation of the foregoing, each Borrower shall at all times be qualified to do
business in each of the states where its Properties are located.

SECTION 5.3 PAYMENT OF IMPOSITIONS AND CLAIMS.

        (A) Except for those matters being contested pursuant to clause (B)
below, the Borrowers will pay (i) all Impositions; (ii) all claims (including
claims for labor, services, materials and supplies) for sums that have become
due and payable and that by law have or may become a Lien upon any of its
properties or assets (hereinafter referred to as the "CLAIMS"); and (iii) all
federal, state and local income taxes, sales taxes, excise taxes and all other
taxes and assessments of the Borrowers on their business, income or assets; in
each instance before any penalty or fine is incurred with respect thereto.

        (B) The Borrowers shall not be required to pay, discharge or remove any
Imposition or Claim relating to a Property so long as the Borrowers contest in
good faith such Imposition,

                                       43

Claim or the validity, applicability or amount thereof by an appropriate legal
proceeding which operates to prevent the collection of such amounts and the sale
of the applicable Property or any portion thereof, so long as: (i) no Event of
Default shall have occurred and be continuing, (ii) prior to the date on which
such Imposition or Claim would otherwise have become delinquent, the Borrowers
shall have given Lender prior written notice of their intent to contest said
Imposition or Claim and shall have deposited with Lender (or with a court of
competent jurisdiction or other appropriate body reasonably approved by Lender)
such additional amounts as are necessary to keep on deposit at all times, an
amount by way of cash (or other form reasonably satisfactory to Lender), equal
to at least one hundred twenty-five percent (125%) of the total of (x) the
balance of such Imposition or Claim then remaining unpaid, and (y) all interest,
penalties, costs and charges accrued or accumulated thereon; (iii) no risk of
sale, forfeiture or loss of any interest in the applicable Property or any part
thereof arises, in Lender's reasonable judgment, during the pendency of such
contest; (iv) such contest does not, in Lender's reasonable determination, have
a Material Adverse Effect; and (v) such contest is based on bona fide, material,
and reasonable claims or defenses. Any such contest shall be prosecuted with due
diligence, and the Borrowers shall promptly pay the amount of such Imposition or
Claim as finally determined, together with all interest and penalties payable in
connection therewith. Lender shall have full power and authority, but no
obligation, to apply any amount deposited with Lender to the payment of any
unpaid Imposition or Claim to prevent the sale or forfeiture of the applicable
Property for non-payment thereof, if Lender reasonably believes that such sale
or forfeiture is threatened.

SECTION 5.4 MAINTENANCE OF INSURANCE.

         The Borrowers will continuously maintain the following described
policies of insurance without cost to Lender (the "INSURANCE POLICIES"):

                  (i) Property insurance against loss and damage by all risks of
physical loss or damage and other risks covered by the so-called extended
coverage endorsement covering the Improvements and personal property on each of
the Properties owned by any of the Borrowers, in amounts not less than the full
insurable replacement value of all Improvements (less building foundations and
footings) and personal property from time to time on the Properties and without
sublimits, and bearing a replacement cost agreed-amount endorsement;

                  (ii) Commercial general liability insurance, including death,
bodily injury and broad form property damage coverage with a combined single
limit in an amount not less than One Million Dollars ($1,000,000) per occurrence
and Two Million Dollars ($2,000,000) in the aggregate for any policy year;

                  (iii) If any of the Properties (other than the Managed
Properties) are in an area prone to geological phenomena, including, but not
limited to, sinkholes, mine subsidence or earthquakes, insurance covering such
risks in an amount equal to 100% of the replacement value with a maximum
permissible deductible of $10,000;

                  (iv) For each Property (other than the Managed Properties)
located in whole or in part in a federally designated "special flood hazard
area", flood insurance in an amount equal

                                       44

to the lesser of (x) the maximum available amount and (y) the replacement cost
of the Improvements and the Borrowers' personal property located on the
applicable Property;

                 (v) An umbrella excess liability policy with a limit of not
less than Forty Million Dollars ($40,000,000) over primary insurance, which
policy shall include coverage for water damage, so-called assumed and
contractual liability coverage, premises medical payment and automobile
liability coverage, and coverage for safeguarding of personalty and shall also
include such additional coverages and insured risks which are acceptable to
Lender;

                 (vi) Business interruption and/or rent loss insurance with an
aggregate limit equal to six (6) months of gross income from the Properties plus
continuing fixed costs for the Properties for a period of not less than six (6)
months;

                 (vii) Worker's Compensation Insurance in statutory amounts, if
any, at all times;

                 (viii) During any period of construction, repair or
restoration, builders "all risk" insurance in an amount equal to not less than
the full insurable value of the Properties applicable construction project;

                 (ix) If the Properties (other than the Managed Properties), or
any of them, are or become a "non-conforming use" under applicable zoning and
building ordinances, or other requirements of the applicable Governmental
Authority, law or ordinance coverage to compensate for the cost of demolition
and the increased cost of construction, if available;

                 (x) Such other insurance as may from time to time be reasonably
required by Lender and which is then customarily required by institutional
lenders for securitized loans secured by similar properties similarly situated,
against other insurable hazards, including, but not limited to, malicious
mischief, vandalism, windstorm and or earthquake, due regard to be given to the
size and type of the Properties, Improvements, fixtures and equipment and their
location, construction and use. Additionally, the Borrowers shall carry such
insurance coverage as Lender may from time to time require if the failure to
carry such insurance would result in a downgrade, qualification or withdrawal of
any class of securities issued in connection with a Securitization (or the
placing of such certificate or other security on negative credit watch or
ratings outlook in contemplation of any such action with respect thereto).
Notwithstanding the provision of this subsection (x):

        All Insurance Policies shall be in content (including, without
limitation, endorsements or exclusions, if any), form, and amounts, and issued
by companies, satisfactory to Lender from time to time and shall name Lender and
its successors and assignees as their interests may appear as an "additional
insured" for each of the liability policies under this Section 5.4 hereof and
shall (except for Worker's Compensation Insurance) contain a waiver of
subrogation clause reasonably acceptable to Lender. All Insurance Policies under
Sections 5.4 (i), (iv), (vi), and (vii) hereof with respect to the Mortgaged
Properties shall contain a Non-Contributory Standard mortgagee clause and a
mortgagee's Loss Payable Endorsement (Form 438 BFU NS), or their equivalents
(such endorsements shall entitle Lender to collect any and all proceeds payable
under all such insurance, with the insurance company waiving any claim or
defense against Lender for

                                       45

premium payment, deductible, self-insured retention or claims reporting
provisions). All Insurance Policies shall provide that the coverage shall not be
modified without (30) days' advance written notice to Lender and shall provide
that no claims shall be paid thereunder to a Person other than Lender without
ten (10) days' advance written notice to Lender. The Borrowers may obtain any
insurance required by this Section through blanket policies; provided, however,
that such blanket policies shall separately set forth the amount of insurance in
force (together with applicable deductibles, and per occurrence limits) with
respect to the Properties (which shall not be reduced by reason of events
occurring on property other than the Properties) and shall afford all the
protections to Lender as are required under this Section. Except as may be
expressly provided above, all policies of insurance required hereunder shall
contain no annual aggregate limit of liability, other than with respect to
liability insurance. If a blanket policy is issued, a certified copy of said
policy shall be furnished, together with a certificate indicating that Lender is
an additional insured (and, if applicable, loss payee) under such policy in the
designated amount. The Borrowers will deliver duplicate originals of all
Insurance Policies, premium prepaid for a period of one (1) year, to Lender and,
in case of Insurance Policies about to expire, the Borrowers will deliver
duplicate originals of replacement policies satisfying the requirements hereof
to Lender prior to the date of expiration; provided, however, if such
replacement policy is not yet available, the Borrowers shall provide Lender with
an insurance certificate executed by the insurer or its authorized agent
evidencing that the insurance required hereunder is being maintained under such
policy, which certificate shall be acceptable to Lender on an interim basis
until the duplicate original of the policy is available. An insurance company
shall not be satisfactory unless such insurance company (a) is licensed or
authorized to issue insurance in the State where the applicable Property is
located and (b) has a claims paying ability rating by the Rating Agencies of "A"
(or its equivalent). Notwithstanding the foregoing, a carrier which does not
meet the foregoing ratings requirement shall nevertheless be deemed acceptable
hereunder provided that such carrier is reasonably acceptable to Lender and the
Borrowers shall obtain and deliver to Lender a Rating Confirmation with respect
to such carrier from each of the Rating Agencies, provided, however, if any
insurance coverage required under this Section 5.4 is maintained by a syndicate
of insurers, the preceding ratings requirements shall be deemed satisfied
(without any required Rating Confirmation) as long as at least seventy-five
percent (75%) of the coverage (if there are four or fewer members of the
syndicate) or at least sixty percent (60%) of the coverage (if there are five or
more members of the syndicate) is maintained with carriers meeting the
claims-paying ability ratings requirements by S&P and Moody's (if applicable)
set forth above and all carriers in such syndicate have a claims-paying ability
rating by S&P of not less than "BBB" and by Moody's of not less than "Baa2" (to
the extent rated by Moody's). The Borrowers shall furnish Lender receipts for
the payment of premiums on such insurance policies or other evidence of such
payment reasonably satisfactory to Lender in the event that such premiums have
not been paid by Lender pursuant to the Loan Agreement. The requirements of this
Section 5.4 shall apply to any separate policies of insurance taken out by the
Borrowers concurrent in form or contributing in the event of loss with the
Insurance Policies. Losses shall be payable to Lender notwithstanding (1) any
act, failure to act or negligence of the Borrowers or their agents or employees,
Lender or any other insured party which might, absent such agreement, result in
a forfeiture or all or part of such insurance payment, other than the willful
misconduct of Lender knowingly in violation of the conditions of such policy,
(2) the occupation or use of the Properties or any part thereof for purposes
more hazardous than permitted by the terms of such policy, (3) any foreclosure
or other action or

                                       46

proceeding taken pursuant to this Loan Agreement or (4) any change in title to
or ownership of the Properties or any part thereof. The property insurance
described in this Section 5.4 hereof shall include "underground hazards"
coverage; "time element" coverage by which Lender shall be assured payment of
all amounts due under the Note, this Loan Agreement and the other Loan
Documents; "extra expense" (i.e., soft costs), clean-up, transit and ordinary
payroll coverage; and "expediting expense" coverage to facilitate rapid repair
or restoration of the Properties. The Insurance Policies shall not contain any
deductible in excess of $250,000.

SECTION 5.5 OPERATION AND MAINTENANCE OF THE PROPERTIES; CASUALTY; CONDEMNATION.

        (A) The Borrowers shall maintain or cause to be maintained in good
repair, working order and condition all material property used in the business
of each Borrower, including the applicable Property, and will make or cause to
be made all appropriate repairs, renewals and replacements thereof. All work
required or permitted under this Loan Agreement shall be performed in a
workmanlike manner and in compliance with all applicable laws.

        (B) (i) In the event of casualty or loss at any of the Properties, the
Borrowers shall give immediate written notice of the same to the insurance
carrier and to Lender and shall promptly commence and diligently prosecute to
completion, in accordance with the terms hereof, the repair and restoration of
the Property as nearly as possible to the Pre-Existing Condition (a
"RESTORATION"). The Borrowers hereby authorize and empower Lender as
attorney-in-fact for the Borrowers (jointly with the Borrowers unless an Event
of Default has occurred and is continuing), or any of them, with respect to
Insurance Proceeds in excess of $1,000,000 to make proof of loss, to adjust and
compromise any claim under insurance policies, to appear in and prosecute any
action arising from such insurance policies, to collect and receive insurance
proceeds (to be held in the Loss Proceeds Reserve Sub-Account pending the
Borrowers' determination with respect to restoration of the affected Property as
set forth in Subsection 5.5(C)), and to deduct therefrom Lender's expenses
incurred in the collection of such proceeds; provided however, that nothing
contained in this Section shall require Lender to incur any expense or take any
action hereunder. The Borrowers further authorize Lender, at Lender's option,
with respect to proceeds in excess of $1,000,000 (a) to hold the balance of such
proceeds to be used to reimburse the Borrowers for the cost of Restoration of
any of the Properties or (b) subject to Subsection 5.5(C), to apply such
Insurance Proceeds to payment of the Obligations whether or not then due, in any
order.

                 (ii) The Borrowers shall promptly give Lender written notice of
any known actual or threatened commencement of any condemnation or eminent
domain proceeding affecting the Properties or any portion thereof and shall
deliver to Lender copies of any and all papers served in connection with such
proceedings. Lender is hereby irrevocably appointed as the Borrowers'
attorney-in-fact, coupled with an interest, with exclusive power to collect,
receive and retain any Condemnation Proceeds (to be held in the Loss Proceeds
Reserve Sub-Account pending the Borrowers' determination with respect to
restoration of the affected Property as set forth in Subsection 5.5(C)) and to
make any compromise or settlement in connection with such proceeding. In
accordance with the terms hereof, the Borrowers shall cause the Condemnation
Proceeds in excess of $1,000,000 which are payable to the Borrowers, to be paid
directly to Lender. If the applicable Property is sold following an Event of
Default, through foreclosure or otherwise, prior to the receipt by Lender of
Condemnation Proceeds, Lender shall have the right,

                                       47

whether or not a deficiency judgment on the Note shall have been sought,
recovered or denied, to receive said Condemnation Proceeds, or a portion thereof
sufficient to pay the Obligations. Notwithstanding the foregoing, the Borrowers
may prosecute any condemnation proceeding and settle or compromise and collect
Condemnation Proceeds of not more than $1,000,000 provided that: (a) no Event of
Default shall have occurred and be continuing, (b) in Lender's reasonable good
faith judgment, such condemnation or taking does not and will not materially
restrict access to the Properties or otherwise have a Material Adverse Effect
and the Property remaining after such condemnation or taking is capable of being
restored to an economically viable whole of substantially the same type which
existed prior to the condemnation or taking or in substantial compliance with
all applicable laws, (c) the Borrowers applies the Condemnation Proceeds to any
reconstruction or repair of the Property necessary as a result of such
condemnation or taking, and (d) the Borrowers promptly commence and diligently
prosecute such reconstruction or repair to completion in accordance with all
applicable laws. Subject to the terms hereof, the Borrowers authorize Lender to
apply such Condemnation Proceeds, after the deduction of Lender's reasonable
expenses incurred in the collection of such Condemnation Proceeds, at Lender's
option, to restoration or repair of the Properties or to payment of the sums
secured by this Mortgage, whether or not then due, in the order determined by
Lender, with the balance, if any, to the Borrowers. Application of any
Condemnation Proceeds to payment of the Obligations pursuant to the foregoing
sentence shall be made with the required Yield Maintenance. Lender shall not
exercise Lender's option to apply such Condemnation Proceeds to payment of the
Obligations provided that each of the conditions (as applicable) to the release
of Loss Proceeds for restoration or repair of the Properties under Section
5.5(C) below have been satisfied with respect to such condemnation awards or
damages.

        (C) Lender shall not exercise Lender's option to apply Loss Proceeds to
payment of the Obligations if all of the following conditions are met: (i) no
Event of Default then exists; (ii) Lender reasonably determines that there will
be sufficient funds to complete the Restoration of the Property to at least
substantially to the condition it was in immediately prior to such casualty and
in compliance with applicable laws (the "PRE-EXISTING CONDITION") and to timely
make all payments due under the Loan Documents during the Restoration of the
affected Property; (iii) Lender reasonably determines that the Net Operating
Income of the Properties (including rental income or business interruption
insurance) will be sufficient to pay principal and interest on the Loan and
Operating Revenues of the Properties, after the Restoration thereof to the
Pre-Existing Condition, will be sufficient to meet all Operating Expenses, and
payments for Reserves; and (iv) Lender determines that the Restoration of the
affected Property to the PreExisting Condition will be completed not later than
six (6) months prior to the Maturity Date. If Lender elects to apply Loss
Proceeds to payment of the Obligations, such application shall be made on the
Payment Date immediately following such election in accordance with the terms of
the Cash Management Agreement. Notwithstanding the foregoing to the contrary,
the Borrowers may, in their reasonable discretion, and within thirty (30) days
of receipt of such Loss Proceeds, elect not to restore or replace a Property, in
which event all Loss Proceeds held in the Loss Proceeds Reserve Sub-Account
shall be applied to payment of the Obligations on the Payment Date immediately
following such election with the required Yield Maintenance.

        (D) Lender shall not be obligated to disburse Loss Proceeds more
frequently than once every calendar month. If Loss Proceeds are applied to the
payment of the Obligations, such application of Loss Proceeds to principal shall
be with the applicable Yield Maintenance and

                                       48

shall not extend or postpone the due dates of the monthly payments due under the
Note or otherwise under the Loan Documents, or change the amounts of such
payments. If Lender elects to apply all of such insurance or condemnation
proceeds toward the repayment of the Obligations, the Borrowers shall (subject
to compliance with SECTION 11.4) be entitled to obtain from Lender a Property
Release (without representation or warranty) of the applicable Property from the
Lien of the Deed of Trust relating to such Property (in which event the
Borrowers shall not be obligated to restore the applicable Property pursuant to
Section 5.5(B) above) provided that the Borrowers pay to Lender (with the
required Yield Maintenance) the amount, if any, by which the Release Price for
such Property exceeds the Loss Proceeds received by Lender and applied to
repayment of the Obligations. Any amount of Loss Proceeds remaining in Lender's
possession after full and final payment and discharge of all Obligations shall
be refunded to, or as directed by, the Borrowers or otherwise paid in accordance
with applicable law. If the Property is sold at foreclosure or if Lender
acquires title to the Property, Lender shall have all of the right, title and
interest of the applicable Borrower in and to any Loss Proceeds and unearned
premiums on Insurance Policies.

        (E) In no event shall Lender be obligated to make disbursements of Loss
Proceeds in excess of an amount equal to the costs actually incurred from time
to time for work in place as part of the Restoration, as certified by the
Borrowers, less a retainage equal to the greater of (x) the actual retainage
required pursuant to the permitted contract, or (y) ten percent (10%) of such
costs incurred until the Restoration has been completed. The retainage shall in
no event be less than the amount actually held back by the Borrowers from
contractors, subcontractors and materialmen engaged in the Restoration. The
retainage shall not be released until Lender is reasonably satisfied that the
Restoration has been completed in accordance with the provisions of this Section
5.5 and that all approvals necessary for the re-occupancy and use of the
Property have been obtained from all appropriate governmental authorities, and
Lender receives final lien waivers and such other evidence reasonably
satisfactory to Lender that the costs of the Restoration have been paid in full
or will be paid in full out of the retainage.

SECTION 5.6 INSPECTION. Each Borrower shall permit any authorized
representatives designated by Lender to visit and inspect during normal business
hours its Properties and its business, including its financial and accounting
records, and to make copies and take extracts therefrom and to discuss its
affairs, finances and business with its officers and independent public
accountants (with such Borrower's representative(s) present), at such reasonable
times during normal business hours and as often as may be reasonably requested.
Unless an Event of Default has occurred and is continuing, Lender shall provide
advance written notice of at least three (3) Business Days prior to visiting or
inspecting any Property or such Borrower's offices.

SECTION 5.7 COMPLIANCE WITH LAWS AND CONTRACTUAL OBLIGATIONS. The Borrowers will
(A) comply with the requirements of all present and future applicable laws,
rules, regulations and orders of any governmental authority in all jurisdictions
in which it is now doing business or may hereafter be doing business, other than
those laws, rules, regulations and orders the noncompliance with which
collectively could not reasonably be expected to have, either individually or in
the aggregate, a Material Adverse Effect, (B) maintain all licenses and permits
now held or hereafter acquired by any Borrower, the loss, suspension, or
revocation of which, or failure to renew, in the aggregate could have a Material
Adverse Effect and (C) perform,

                                       49

observe, comply and fulfill all of its material obligations, covenants and
conditions contained in any Contractual Obligation.

SECTION 5.8 FURTHER ASSURANCES. The Borrowers shall, from time to time, execute
and/or deliver such documents, instruments, agreements, financing statements,
and perform such acts as Lender at any time may reasonably request to evidence,
preserve and/or protect the Collateral at any time securing or intended to
secure the Obligations and/or to better and more effectively carry out the
purposes of this Loan Agreement and the other Loan Documents.

SECTION 5.9 PERFORMANCE OF AGREEMENTS AND LEASES. Each Borrower Party shall duly
and punctually perform, observe and comply in all material respects with all of
the terms, provisions, conditions, covenants and agreements on its part to be
performed, observed and complied with (i) hereunder and under the other Loan
Documents to which it is a party, (ii) under all Material Agreements and Leases
and (iii) all other agreements entered into or assumed by such Person in
connection with the Properties, and will not suffer or permit any material
default or event of default (giving effect to any applicable notice requirements
and cure periods) to exist under any of the foregoing except where the failure
to perform, observe or comply with any agreement referred to in this clause
(iii) would not reasonably be expected to have a Material Adverse Effect.
Notwithstanding the foregoing to the contrary, the Borrowers shall be permitted
to terminate any Site Management Agreement which the Borrowers reasonably deem
necessary in accordance with prudent business practices, provided that (i) the
Borrowers provide written notice to Lender of such determination not later than
thirty (30) days prior to such termination, (ii) together with such notice the
Borrowers provide supporting information reasonably acceptable to Lender that
following such termination the DSCR will be equal to or greater than the DSCR
immediately prior to such termination, (iii) if the aggregate Allocated Loan
Amount with respect to (x) each such Property for which termination has occurred
under this Section 5.9, Section 5.23(A), and Section 5.24(A) and (y) the
Property for which a termination is proposed, is greater than five percent (5%)
of the Principal Amount of the Loan at Closing, the Borrowers have delivered a
Rating Confirmation, and (iv) following such termination, such Property will be
owned and managed by a Person other than the Borrowers or any of their
Affiliates.

SECTION 5.10 LEASES. Except for security deposits, no Leases shall provide for
payment of rent more than one month in advance, and the Borrowers shall not
under any circumstances collect any such rent more than one month in advance,
unless in either such instance such Rents which constitute Advance Rents Reserve
Deposits are deposited into the Advance Rents Reserve SubAccount to be applied
in accordance with the Cash Management Agreement. The Borrowers, at Lender's
request, shall furnish Lender with executed copies of all Leases hereafter made.
Each new Lease (which shall not include the addition of new sites pursuant to
existing master Leases) shall specifically provide that such Lease (i) is
subordinate to the Deeds of Trust; (ii) that the tenant attorns to Lender, such
attornment to be effective upon Lender's acquisition of title to the Property;
(iii) that the tenant agrees to execute such further evidences of attornment as
Lender may from time to time request; (iv) that the attornment of the tenant
shall not be terminated by foreclosure; (v) that in no event shall Lender, as
holder of the Deeds of Trust or as successor landlord, be liable to the tenant
for any act or omission of any prior landlord or for any liability or obligation
of any prior landlord occurring prior to the date that Lender or any subsequent
owner acquire title to the Property; and (vi) that Lender may, at Lender's
option, accept or reject such attornment.

                                       50

SECTION 5.11 MANAGEMENT AGREEMENT.

        (A) The Borrowers shall cause Manager to manage the Properties in
accordance with the Management Agreement. The Borrowers shall (i) perform and
observe all of the material terms, covenants and conditions of the Management
Agreement on the part of each Borrower to be performed and observed, (ii)
promptly notify Lender of any notice to any of the Borrowers of any material
default under the Management Agreement of which it is aware, and (iii) prior to
termination of the Manager in accordance with Section 5.11(C) hereof, Borrower
shall renew the Management Agreement prior to each expiration date thereunder in
accordance with its terms. If any of the Borrowers shall default in the
performance or observance of any material term, covenant or condition of the
Management Agreement on the part of the Borrowers to be performed or observed,
then, without limiting Lender's other rights or remedies under this Agreement or
the other Loan Documents, and without waiving or releasing the Borrowers from
any of their obligations hereunder or under the Management Agreement, Lender
shall have the right, upon prior written notice to the Borrowers, but shall be
under no obligation, to pay any sums and to perform any act as may be reasonably
appropriate to cause such material conditions of the Management Agreement on the
part of the Borrowers to be performed or observed.

        (B) The Borrowers shall not surrender, terminate, cancel, or modify
(other than nonmaterial changes), the Management Agreement, or enter into any
other Management Agreement with any new Manager (other than an Acceptable
Manager), or consent to the assignment by the Manager of its interest under the
Management Agreement, in each case without delivery of Rating Confirmations from
each of the Rating Agencies and written consent of the Lender. If at any time
Lender consents to the appointment of a new Manager, or if an Acceptable Manager
shall become the Manager, such new Manager, or the Acceptable Manager, as the
case may be, and the Borrowers shall, as a condition of Lender's consent, or
with respect to an Acceptable Manager, prior to commencement of its duties as
Manager, execute a subordination of management agreement in substantially the
form delivered in connection with the closing of the Loan.

        (C) Lender shall have the right to require that the Manager be replaced
with a Person chosen by the Borrowers (or, if an Event of Default has occurred
and is then continuing, Lender) and reasonably acceptable to Lender, upon the
earliest to occur of any one or more of the following events: (i) an Event of
Default has occurred and is then continuing, (ii) thirty (30) days after notice
from Lender to the Borrowers if Manager has engaged in fraud, gross negligence
or willful misconduct arising from or in connection with its performance under
the Management Agreement, (iii) thirty (30) days after notice from Lender to the
Borrowers (a) following the Anticipated Repayment Date, or (b) if the DSCR is
less than 1.1:1 and Lender reasonably determines that such decline in the DSCR
is primarily attributable to acts or omissions of the Manager rather than
factors affecting the Borrowers' industry generally or (iv) Manager defaults
under the Management Agreement and such default is reasonably likely to have a
Material Adverse Effect.

SECTION 5.12 RESERVED.

SECTION 5.13 DEPOSITS; APPLICATION OF RECEIPTS. The Borrowers will deposit all
Receipts into, and otherwise comply with, the Accounts established from time to
time hereunder. Subject to

                                       51

interest has been paid, (iv) whether any offsets or defenses exist against the
Obligations, and if any such offsets or defenses are alleged to exist, the
nature thereof shall be set forth in detail and (v) that this Loan Agreement,
the Note, the Deeds of Trust and the other Loan Documents are legal, valid and
binding obligations of the Borrowers and have not been modified or amended, or
if modified or amended, describing such modification or amendments.

        (B) Within ten (10) Business Days following a written request by the
Borrowers, Lender shall provide to the Borrowers a duly acknowledged written
statement setting forth the amount of the outstanding principal balance of the
Loan, the date to which interest has been paid, and whether Lender has provided
the Borrowers with written notice of any Event of Default. Compliance by Lender
with the requirements of this Section shall be for informational purposes only
and shall not be deemed to be a waiver of any rights or remedies of Lender
hereunder or under any other Loan Document.

SECTION 5.15 INDEBTEDNESS. The Borrowers will not directly or indirectly create,
incur, assume, guaranty, or otherwise become or remain directly or indirectly
liable with respect to any Indebtedness except for the following (collectively,
"PERMITTED INDEBTEDNESS"):

        (A) The Obligations;

        (B) (i) Unsecured trade payables not evidenced by a note and arising out
of purchases of goods or services in the ordinary course of business and (ii)
Indebtedness incurred in the financing of equipment or other personal property
used at any Property in the ordinary course of business, provided that (a) each
such trade payable is payable not later than ninety (90) days after the original
invoice date and is not overdue by more than thirty (30) days, and (b) the
aggregate amount of such trade payables and Indebtedness relating to financing
of equipment and personal property or otherwise referred to in clauses (i) and

In no event shall any Indebtedness other than the Loan be secured, in whole or
in part, by the Properties or any portion thereof or interest therein,

SECTION 5.16 NO LIENS. The obligations of each Borrower under this Section are
in addition to and not in limitation of its obligations under Article XI herein.
The Borrower shall not create, incur, assume or permit to exist any Lien on or
with respect to the Properties, any other Collateral or any such direct or
indirect ownership interest in the Borrowers, except the Permitted Encumbrances.

                                       52

Borrower Party shall directly or indirectly create or become or be liable with
respect to any Contingent Obligation.

SECTION 5.18 RESTRICTION ON FUNDAMENTAL CHANGES. Except as otherwise expressly
permitted in this Loan Agreement, no Borrower Party shall, or shall permit any
other Person to, (i) amend, modify or waive any term or provision of such
Borrower Party's partnership agreement, certificate of limited partnership,
articles of incorporation, by-laws, articles of organization, operating
agreement or other organizational documents so as to violate or permit the
violation of the single-purpose entity provisions set forth in Article IX,
unless required by law; or (ii) liquidate, wind-up or dissolve such Borrower
Party or Manager.

SECTION 5.19 TRANSACTIONS WITH RELATED PERSONS. The Borrowers shall not directly
or indirectly enter into or permit to exist any transaction (including the
purchase, sale, lease or exchange of any property or the rendering of any
service) with any Related Person of any of the Borrowers or with any director,
officer or employee of any Borrower Party, except transactions in the ordinary
course of and pursuant to the reasonable requirements of the business of the
Borrowers and upon fair and reasonable terms and are no less favorable to any of
the Borrowers than would be obtained in a comparable arm's length transaction
with a Person that is not a Related Person of any Borrower. The Borrowers shall
not make any payment or permit any payment to be made to any Related Person of
any of the Borrowers when or as to any time when any Event of Default shall
exist except as may be permitted by Lender pursuant to the terms of the Cash
Management Agreement.

SECTION 5.20 BANKRUPTCY, RECEIVERS, SIMILAR MATTERS.

        (A) VOLUNTARY CASES. The Borrower Parties shall not commence any
voluntary case under the Bankruptcy Code or under any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect.

        (B) INVOLUNTARY CASES, RECEIVERS, ETC. The Borrower Parties shall not
apply for, consent to, or aid, solicit, support, or otherwise act, cooperate or
collude to cause the appointment of or taking possession by, a receiver, trustee
or other custodian for all or a substantial part of the assets of any Borrower.
As used in this Loan Agreement, an "INVOLUNTARY BORROWER BANKRUPTCY" shall mean
any involuntary case under the Bankruptcy Code or any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect, in which any of the
Borrowers is a debtor or any portion of the Properties is property of the estate
therein. The Borrowers shall not file a petition for, consent to the filing of a
petition for, or aid, solicit, support, or otherwise act, cooperate or collude
to cause the filing of a petition for an Involuntary Borrower Bankruptcy. In any
Involuntary Borrower Bankruptcy, no Borrower Party shall, without the prior
written consent of Lender, consent to the entry of any order, file any motion,
or support any motion (irrespective of the subject of the motion), and the
Borrowers shall not file or support any plan of reorganization. The Borrowers
having any interest in any Involuntary Borrower Bankruptcy shall do all things
reasonably requested by Lender to assist Lender in obtaining such relief as
Lender shall seek, and shall in all events vote as directed by Lender. Without
limitation of the foregoing, each such Borrower shall do all things reasonably
requested

                                       53

by Lender to support any motion for relief from stay or plan of reorganization
proposed or supported by Lender.

SECTION 5.21 ERISA.

        (A) NO ERISA PLANS. None of the Borrower Parties will establish any
Employee Benefit Plan or Multiemployer Plan, or will commence making
contributions to (or become obligated to make contributions to) any Employee
Benefit Plan or Multiemployer Plan.

        (B) COMPLIANCE WITH ERISA. The Borrowers shall not: (i) engage in any
nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of
the IRC; or (ii) except as may be necessary to comply with applicable laws,
establish or amend any Employee Benefit Plan which establishment or amendment
could result in liability to the Borrowers or any ERISA Affiliate or increase
the obligation of the Borrowers, provided that the Borrower shall not be in
default of this covenant if, in either case, any portion of the Loan has been,
or will be, funded with plan assets of any employee benefit plan that either (x)
is subject to Title I of ERISA or any plan that is covered by Section 4975 of
the Code (unless the Lender is eligible to apply for one or more exemptions such
that the Loan will not constitute a nonexempt prohibited transaction under
Section 406 of ERISA) or (y) could subject a Borrower Party or its Affiliates to
an excise tax under Section 4975 of the IRC.

        (C) NO PLAN ASSETS. The Borrowers shall not at any time during the term
of this Loan Agreement become (1) an employee benefit plan defined in Section
3(3) of ERISA which is subject to ERISA, (2) a plan as defined in Section
4975(e)(1) of the IRC which is subject to Section 4975 of the IRC, (3) a
"governmental plan" within the meaning of Section 3(32) of ERISA or (4) an
entity any of whose underlying assets constitute "plan assets" of any such
employee benefit plan, plan or governmental plan for purposes of Title I of
ERISA, Section 4975 of the IRC or any state statutes applicable to the Borrowers
regulating investments of governmental plans.

SECTION 5.22 PRESS RELEASE. The Borrowers shall not, and shall not permit any
other Person within its control to, disclose the name of Lender or terms of this
Loan Agreement or the Loan Documents in any press release without the prior
written consent of Lender, which shall not be unreasonably withheld.
Notwithstanding the foregoing to the contrary, the Borrowers shall be permitted
to make such filings and disclosures with respect to the Loan as are required by
law.
SECTION 5.23 GROUND LEASES.

        (A) NO MODIFICATION. The Borrowers shall not modify or amend any
material substantive or economic terms of, or, subject to the terms of Section
11.5 hereof, terminate or surrender any Ground Lease, in each case without the
prior written consent of Lender, which consent may be withheld by Lender in its
sole and absolute discretion. Any attempted or purported material modification,
amendment, or any surrender or termination of any Ground Lease without Lender's
prior written consent shall be null and void and of no force or effect.
Notwithstanding the foregoing to the contrary, the Borrowers shall be permitted,
without Lender's consent, to extend the terms of the Ground Lease, and the
Borrowers shall be permitted to terminate any Ground Lease which the Borrowers
reasonably deem necessary in accordance

                                       54

with prudent business practices, provided that (i) the Borrowers provide written
notice to Lender of such determination not later than thirty (30) days prior to
such termination, (ii) together with such notice the Borrowers provide
supporting information reasonably acceptable to Lender that following such
termination the DSCR will be equal to or greater than the DSCR immediately prior
to such termination, (iii) if the aggregate Allocated Loan Amount with respect
to (x) each such Property for which a termination has occurred under this
Section 5.23(A), Section 5.9, and Section 5.24(A) and (y) the Property for which
a termination is proposed is greater than five percent (5%) of the Principal
Amount of the Loan at Closing, the Borrowers have delivered a Rating
Confirmation, and (iv) following such termination such Property is not held by
any Affiliate of the Borrowers.

        (B) PERFORMANCE OF GROUND LEASES. The Borrowers shall fully perform as
and when due each and all of its obligations under each Ground Lease in
accordance with the terms of such Ground Lease, and shall not cause or suffer to
occur any material breach or default in any of such obligations. The Borrowers
shall exercise any option to renew or extend any Ground Lease and if the
Borrowers elect not to renew a Ground Lease (which shall only be permitted if
the Borrowers would be entitled to terminate such Ground Lease pursuant to
clause (A) above) the Borrowers shall give Lender thirty (30) days prior written
notice of the Borrowers' intention not to renew such Ground Lease. If the
Borrowers fail to renew a Ground Lease which is required to be renewed pursuant
to this Section 5.23(B), Lender shall have the right to renew such Ground Lease
on behalf of the Borrowers. Notwithstanding that certain of the obligations of
the Borrowers under this Loan Agreement may be similar or identical to certain
of the obligations of the Borrowers under the Ground Leases, all of the
obligations of the Borrowers under this Loan Agreement are and shall be separate
from and in addition to its obligations under the Ground Leases.

        (C) NOTICE OF DEFAULT. If any of the Borrowers shall have or receive any
written notice that any Ground Lease Default has occurred, then the Borrowers
immediately shall notify Lender in writing of the same and immediately deliver
to Lender a true and complete copy of each such notice. Further, the Borrowers
shall provide such documents and information as Lender shall reasonably request
concerning the Ground Lease Default.

        (D) LENDER'S RIGHT TO CURE. If any Ground Lease Default shall occur and
be continuing, or if any Ground Lessor asserts that a Ground Lease Default has
occurred (whether or not the Borrowers question or deny such assertion), then,
subject to (i) the terms and conditions of the applicable Ground Lease, and (ii)
the Borrowers' right to terminate Ground Leases in accordance with Section
5.23(A) hereof, Lender, upon five (5) Business Days' prior written notice to the
Borrowers, unless Lender reasonably determines that a shorter period (or no
period) of notice is necessary to protect Lender's interest in the Ground Lease,
may (but shall not be obligated to) take any action that Lender deems reasonably
necessary, including, without limitation, (i) performance or attempted
performance of the applicable Borrower's obligations under the applicable Ground
Lease, (ii) curing or attempting to cure any actual or purported Ground Lease
Default, (iii) mitigating or attempting to mitigate any damages or consequences
of the same and (iv) entry upon the applicable Ground Leased Property for any or
all of such purposes. Upon Lender's request, each Borrower shall submit
satisfactory evidence of payment or performance of any of its obligations under
each Ground Lease. Lender may pay and expend such sums of money as Lender in its
sole discretion deems necessary or desirable for any such

                                       55

purpose, and the Borrowers shall pay to Lender within five (5) Business Days of
the written demand of Lender all such sums so paid or expended by Lender,
together with interest thereon from the date of expenditure at the Default Rate.

        (E) LEGAL ACTION. The Borrowers shall not commence any action or
proceeding against any Ground Lessor or affecting or potentially affecting any
Ground Lease or the Borrowers' or Lender's interest therein, the effect of which
could cause an event of default or termination of any such Ground Lease, without
the prior written consent of Lender, which consent shall not be unreasonably
withheld, conditioned or delayed. The Borrowers shall notify Lender immediately
if any action or proceeding shall be commenced between any Ground Lessor and
either Borrower, or affecting or potentially affecting any Ground Lease or
either Borrower's or Lender's interest therein (including, without limitation,
any case commenced by or against any Ground Lessor under the Bankruptcy Code).
Lender shall have the option, exercisable upon notice from Lender to the
Borrowers, to participate in any such action or proceeding with counsel of
Lender's choice. The Borrowers shall cooperate with Lender, comply with the
reasonable instructions of Lender, execute any and all powers, authorizations,
consents or other documents reasonably required by Lender in connection
therewith, and shall not settle any such action or proceeding without the prior
written consent of Lender, which consent shall not be unreasonably withheld,
conditioned or delayed.

        (F) BANKRUPTCY.

            (i) If any Ground Lessor shall reject any Ground Lease under or
pursuant to Section 365 of the Bankruptcy Code, the Borrowers shall not elect to
treat the Ground Lease as terminated but shall elect to remain in possession of
the applicable Ground Leased Property and the leasehold estate under such Ground
Lease. The lien of the Deed of Trust covering such Property does and shall
encumber and attach to all of the Borrowers' rights and remedies at any time
arising under or pursuant to Section 365 of the Bankruptcy Code, including
without limitation, all of such Borrower's rights to remain in possession of
such Property and the leasehold estate.

            (ii) The Borrowers acknowledge and agree that in any case commenced
by or against the Borrowers under the Bankruptcy Code, Lender by reason of the
liens and rights granted under the Deed of Trust covering such Property and the
Loan Documents shall have a substantial and material interest in the treatment
and preservation of such Borrower's rights and obligations under such Ground
Lease, and that such Borrower shall, in any such bankruptcy case, provide to
Lender immediate and continuous reasonably adequate protection of such
interests. Each Borrower and Lender agree that such adequate protection shall
include but shall not necessarily be limited to the following:

            (a) Lender shall be deemed a party to the Ground Lease (but shall
not have any obligations thereunder) for purposes of Section 365 of the
Bankruptcy Code, and shall, provided that, prior to an Event of Default, no such
action by Lender would adversely and materially affect the Borrowers' ability to
prosecute, or defend, any such claims asserted therein, have standing to appear
and act as a party in interest in relation to any matter arising out of or
related to the Ground Lease or such Property.

                                       56

            (b) The Borrowers shall serve Lender with copies of all notices,
pleadings and other documents relating to or affecting the Ground Lease or the
applicable Property. Any notice, pleading or document served by the Borrowers on
any other party in the bankruptcy case shall be contemporaneously served by such
Borrower on Lender, and any notice, pleading or document served upon or received
by such Borrower from any other party in the bankruptcy case shall be served by
such Borrower on Lender promptly upon receipt by such Borrower.

            (c) Upon written request of Lender, the Borrowers shall assume the
Ground Lease, and shall take such steps as are necessary to preserve such
Borrower's right to assume the Ground Lease, including without limitation using
commercially reasonable efforts to obtain extensions of time to assume or reject
the Ground Lease under Subsection 365(d) of the Bankruptcy Code to the extent it
is applicable.

        (G) If the Borrowers or the applicable Ground Lessor seeks to reject any
Ground Lease or have the Ground Lease deemed rejected, then prior to the hearing
on such rejection Lender shall, subject to applicable law, be given no less than
twenty (20) days' notice and opportunity to elect in lieu of rejection to have
the Ground Lease assumed and assigned to a nominee of Lender. If Lender shall so
elect to assume and assign the Ground Lease, then the Borrowers shall, subject
to applicable law, continue any request to reject the Ground Lease until after
the motion to assume and assign has been heard. If Lender shall not elect to
assume and assign the Ground Lease, then Lender may, subject to applicable law,
obtain in connection with the rejection of the Ground Lease a determination that
the applicable Ground Lessor, at Lender's option, shall (1) agree to terminate
the Ground Lease and enter into a new lease with Lender on the same terms and
conditions as the Ground Lease, for the remaining term of the Ground Lease, or
(2) treat the Ground Lease as breached and provide Lender with the rights to
cure defaults under the Ground Lease and to assume the rights and benefits of
the Ground Lease.

            Each Borrower shall join with and support any request by Lender to
grant and approve the foregoing as necessary for adequate protection of Lender's
interests. Notwithstanding the foregoing, Lender may seek additional terms and
conditions, including such economic and monetary protections as it deems
reasonably appropriate to adequately protect its interests, and any request for
such additional terms or conditions shall not delay or limit Lender's right to
receive the specific elements of adequate protection set forth herein.

            Each Borrower hereby appoints Lender as its attorney in fact to act
on behalf of Lender in connection with all matters relating to or arising out of
the assumption or rejection of any Ground Lease, in which the other party to the
lease is a debtor in a case under the Bankruptcy Code. This grant of power of
attorney is present, unconditional, irrevocable, durable and coupled with an
interest.

SECTION 5.24 EASEMENTS.

        (A) NO MODIFICATION. The Borrowers shall not modify or amend any
material substantive or economic terms of, or, subject to the terms of Section
11.5 hereof, terminate or surrender any Easement, in each case without the prior
written consent of Lender, which consent may be withheld by Lender in its sole
and absolute discretion. Any attempted or purported material modification,
amendment, or any surrender or termination of any Easement without

                                       57

Lender's prior written consent shall be null and void and of no force or effect.
Notwithstanding the foregoing to the contrary, the Borrowers shall be permitted,
without Lender's consent, to extend the Terms of the Easement, and the Borrowers
shall be permitted to terminate any Easement which the Borrowers reasonably deem
necessary in accordance with prudent business practices, provided that (i) the
Borrowers provide written notice to Lender of such determination not later than
thirty (30) days prior to such termination, (ii) together with such notice the
Borrowers provide supporting information reasonably acceptable to Lender that
following such termination the DSCR will be equal to or greater than the DSCR
immediately prior to such termination, (iii) if the aggregate Allocated Loan
Amount with respect to (x) each such Property for which a termination has
occurred under this Section 5.24(A), Section 5.9 and Section 5.23(A) and (y) the
Property for which a termination is proposed is greater than five percent (5%)
of the Principal Amount of the Loan at Closing, the Borrowers have delivered a
Rating Confirmation, and (iv) following such termination such Property is not
held by any Affiliate of the Borrowers.

        (B) PERFORMANCE OF EASEMENTS. The Borrowers shall fully perform as and
when due each and all of its obligations under each Easement in accordance with
the terms of such Easement, and shall not cause or suffer to occur any material
breach or default in any of such obligations. Notwithstanding that certain of
the obligations of the Borrowers under this Loan Agreement may be similar or
identical to certain of the obligations of the Borrowers under the Easements,
all of the obligations of the Borrowers under this Loan Agreement are and shall
be separate from and in addition to its obligations under the Easements.

        (C) NOTICE OF DEFAULT. If any of the Borrowers shall have or receive any
written notice that any Easement Default has occurred, then the Borrowers
immediately shall notify Lender in writing of the same and immediately deliver
to Lender a true and complete copy of each such notice. Further, the Borrowers
shall provide such documents and information as Lender shall reasonably request
concerning the Easement Default.

        (D) LENDER'S RIGHT TO CURE. If any Easement Default shall occur and be
continuing, or if the fee owner asserts that an Easement Default has occurred
(whether or not the Borrowers question or deny such assertion), then, subject to
the terms and conditions of the applicable Easement Lender, upon five (5)
Business Days' prior written notice to the Borrowers, unless Lender reasonably
determines that a shorter period (or no period) of notice is necessary to
protect Lender's interest in the Easement, may (but shall not be obligated to)
take any action that Lender deems reasonably necessary, including, without
limitation, (i) performance or attempted performance of the applicable
Borrower's obligations under the applicable Easement, (ii) curing or attempting
to cure any actual or purported Easement Default, (iii) mitigating or attempting
to mitigate any damages or consequences of the same and (iv) entry upon the
applicable Property for any or all of such purposes. Upon Lender's request, each
Borrower shall submit satisfactory evidence of payment or performance of any of
its obligations under each Easement. Lender may pay and expend such sums of
money as Lender in its sole discretion deems necessary or desirable for any such
purpose, and the Borrowers shall pay to Lender within five (5) Business Days of
the written demand of Lender all such sums so paid or expended by Lender,
together with interest thereon from the date of expenditure at the Default Rate.

SECTION 5.25 INDEBTEDNESS OF GSI. Prior to the date that the aggregate tangible
assets of the Borrowers is less than twenty-five percent (25%) of the tangible
assets of GSI (all calculated in

                                       58

accordance with GAAP and determined based upon the Financial Statements
delivered pursuant to Section 5.1), the Borrowers shall not permit GSI to incur
any unsecured Indebtedness for borrowed money under a note, bond, loan agreement
or similar document, without delivering a Rating Confirmation to Lender.

SECTION 5.26 LENDER'S EXPENSES. The Borrowers shall pay, on demand by Lender,
all reasonable out-of-pocket expenses, charges, costs and fees (including
reasonable attorneys' fees and expenses) in connection with the negotiation,
documentation, closing, administration, servicing, enforcement interpretation,
and collection of the Loan and the Loan Documents, and in the preservation and
protection of Lender's rights hereunder and thereunder. Without limitation the
Borrowers shall pay all costs and expenses, including reasonable attorneys'
fees, incurred by Lender in any case or proceeding under the Bankruptcy Code (or
any law succeeding or replacing any of the same).

                                   ARTICLE VI
                                    RESERVES

SECTION 6.1 SECURITY INTEREST IN RESERVES; OTHER MATTERS PERTAINING TO RESERVES.

        (A) The Borrowers hereby pledge, assign and grant to Lender a security
interest in and to all of the Borrowers' right, title and interest in and to the
Account Collateral, including the Reserves, as security for payment and
performance of all of the Obligations hereunder and under the Note and the other
Loan Documents. The Reserves constitute Account Collateral and are subject to
the security interest in favor of Lender created herein and all provisions of
this Loan Agreement and the other Loan Documents pertaining to Account
Collateral.

        (B) In addition to the rights and remedies provided in Article VII and
elsewhere herein, upon the occurrence and during the continuance of any Event of
Default, Lender shall have all rights and remedies pertaining to the Reserves as
are provided for in any of the Loan Documents or under any applicable law.
Without limiting the foregoing, upon and at all times after the occurrence and
during the continuance of an Event of Default, Lender in its sole and absolute
discretion, may use the Reserves (or any portion thereof) for any purpose,
including but not limited to any combination of the following: (i) payment of
any of the Obligations including the Yield Maintenance (if any) applicable upon
such payment in such order as Lender may determine in its sole discretion;
provided, however, that such application of funds shall not cure or be deemed to
cure any default; (ii) reimbursement of Lender for any actual losses or expenses
(including, without limitation, reasonable legal fees) suffered or incurred as a
result of such Event of Default; (iii) payment for the work or obligation for
which such Reserves were reserved or were required to be reserved; and (iv)
application of the Reserves in connection with the exercise of any and all
rights and remedies available to Lender at law or in equity or under this Loan
Agreement or pursuant to any of the other Loan Documents. Nothing contained in
this Loan Agreement shall obligate Lender to apply all or any portion of the
funds contained in the Reserves during the continuance of an Event of Default to
payment of the Loan or in any specific order of priority.

                                       59

SECTION 6.2 FUNDS DEPOSITED WITH LENDER.

        (A) INTEREST, OFFSETS. Except only as expressly provided otherwise
herein, all funds of the Borrowers which are deposited with Lock Box Account
Bank as Reserves hereunder shall be held by Lock Box Account Bank in one or more
Permitted Investments, such Permitted Investments, prior to an Event of Default,
to be as directed by the Borrowers. All interest which accrues on the Reserves
shall be taxable to the Borrowers and shall be added to and disbursed in the
same manner and under the same conditions as the principal sum on which said
interest accrued. The amount of actual losses sustained on a liquidation of a
Permitted Investment shall be deposited by the Borrowers into the Lock Box
Account no later than three (3) Business Days following such liquidation.
Additional provisions pertaining to investments are set forth in Article VII.
After repayment of all of the Obligations, all funds held as Reserves will be
promptly returned to, or as directed by, the Borrowers.

        (B) FUNDING AT CLOSING. The Borrowers shall deposit with Lender the
amounts necessary to fund each of the Reserves as set forth below. Deposits into
the Reserves at Closing may occur by deduction from the amount of the Loan that
otherwise would be disbursed to the Borrowers, followed by deposit of the same
into the applicable Sub-Account or Account of the Lock Box Account in accordance
with the Cash Management Agreement on the Closing Date. Notwithstanding such
deductions, the Loan shall be deemed for all purposes to be fully disbursed at
Closing.

SECTION 6.3 IMPOSITIONS AND INSURANCE RESERVE. On the Closing Date, the
Borrowers shall deposit with Lock Box Account Bank $3,539,455 and, pursuant to
the Cash Management Agreement, the Borrowers shall deposit monthly, on each
Payment Date commencing on the Payment date in March 2004, 1/12th of the annual
charges (as reasonably estimated by Lender) for all Impositions (excluding,
however, personal property taxes) and all Insurance Premiums payable with
respect to the Properties hereunder (said funds, together with any interest
thereon and additions thereto, the "IMPOSITIONS AND INSURANCE RESERVE"). The
initial amount of the monthly deposit to be made to the Impositions and
Insurance Reserve from and after the date hereof is $1,500,000.00. The Borrowers
shall also deposit with Lock Box Account Bank within ten (10) Business Days of
the written demand by Lender, to be added to and included within such reserve, a
sum of money which Lender reasonably estimates, together with such monthly
deposits, will be sufficient to make the payment of each such charge at least
ten (10) Business Days prior to the date initially due. The Borrowers shall
provide Lender with bills or a statement of amounts due for the next calendar
month which shall be accompanied by an Officer's Certificate and such other
documents as may be reasonably required to establish the amounts required to be
paid in the following calendar month at least five (5) days prior to the date on
which each payment shall first become subject to penalty or interest if not
paid, or if paid, copies of paid bills. So long as (i) no Event of Default has
occurred and is continuing, (ii) the Borrowers have provided Lender with the
foregoing materials in a timely manner, and (iii) sufficient funds are held by
Lender for the payment of the Impositions and Insurance Premiums relating to the
Properties, as applicable, Lender shall at the Borrowers' election, (x) pay said
items, (y) disburse to the Borrowers from such Reserve an amount sufficient to
pay said items, or (z) reimburse the Borrowers for items previously paid by the
Borrowers. Interest shall accrue in favor of the Borrowers on funds in the
Impositions and Insurance Reserve.

                                       60

SECTION 6.4 ADVANCE RENTS RESERVE SUB-ACCOUNT. On the Closing Date, the
Borrowers shall deposit with Lock Box Bank $1,131,000 and, pursuant to the Cash
Management Agreement, the Borrowers shall deposit, or instruct Lock Box Bank to
deposit, (i) the Annual Advance Rents Reserve Deposit not later than the third
(3rd) Business Day of February of each calendar year, and (ii) the Quarterly
Advance Rents Reserve Deposit not later than the third (3rd) Business Day of
February, May, August and November of each calendar year, such amounts to be
deposited into a sub-account of the Lock Box Account (said sub-account, the
"Advance Rents Reserve Sub-Account") for deposit of such Advance Rents Reserve
Deposit and such Advance Rents Reserve Deposit shall be held, allocated and
disbursed in accordance with the terms and conditions of the Cash Management
Agreement. The Advance Rents Reserve Sub-Account shall be under the sole
dominion and control of Lender and/or its designee including any Servicer of the
Loan, and the Borrowers shall have no rights to control or direct the investment
or payment of funds therein except as expressly provided herein.

SECTION 6.6 RESERVED.

SECTION 6.7 RESERVED.

SECTION 6.8 CASH TRAP RESERVE. (i) If, at any time prior to the Anticipated
Repayment Date, a Cash Trap Event shall occur, then, from and after the date
that it is determined that a Cash Trap Event has occurred (which shall be based
upon the financial reporting required to be delivered pursuant to Section
5.1(A)(iv)) and for so long as such Cash Trap Event continues to exist, all
Excess Cash Flow (except as otherwise expressly provided below) shall be
deposited with Lender (or its Servicer or agent) and held in the Lock Box
Account in accordance with the terms of the Cash Management Agreement (said
funds, together with any interest thereon, the "CASH TRAP RESERVE"). A "CASH
TRAP EVENT" shall occur as of the last day of any calendar quarter when the Debt
Service Coverage Ratio is equal to or less than the Cash Trap DSCR, and shall
continue to exist until such time as the Debt Service Coverage Ratio exceeds the
Cash Trap DSCR for two (2) consecutive calendar quarters. If as of the last day
of any calendar quarter the Debt Service Coverage Ratio is less than the Minimum
DSCR, Lender will apply any amounts in the Cash Trap Reserve to payment of the
Loan on the next Payment Date (including any required Yield Maintenance). Any
funds on deposit in the Cash Trap Reserve shall continue to be held as
additional Collateral in accordance with this Section 6.8. At any time prior to
the Anticipated Repayment Date, provided that no Event of Default exists and the
Cash Trap DSCR test has been satisfied for two (2) consecutive calendar quarters
(as determined above), any funds remaining in the Cash Trap Reserve shall be
released to the Borrowers. The existence of a Cash Trap Event shall be
determined by Lender in its reasonable good faith determination. Notwithstanding
any provision herein to the contrary, (x) during the continuance of an Event of
Default, and (y) following the Anticipated Repayment Date, all funds on deposit
in the Cash Trap Reserve and any subsequent Excess Cash Flow may be applied by
Lender to payment of the Loan (including payment of Yield Maintenance, if any)
or other Obligations as Lender may elect.

SECTION 7.1 ESTABLISHMENT OF DEPOSIT ACCOUNT AND LOCK BOX ACCOUNT.

        (A) (i) DEPOSIT ACCOUNT. On or before the Closing Date, one or more
deposit accounts, which shall be Eligible Accounts, shall be established at the
Borrowers' sole cost and expense in the name of Lender, as secured party
hereunder (said accounts, and any accounts replacing same in accordance with
this Loan Agreement and the Deposit Account Agreement, collectively, the
"DEPOSIT ACCOUNT") with one or more financial institutions reasonably approved
by Lender (collectively, the "DEPOSIT BANK"), pursuant to one or more agreements
(collectively, the "DEPOSIT ACCOUNT AGREEMENT") substantially similar to
Lender's form or otherwise in form and substance reasonably acceptable to
Lender, executed and delivered by the Borrowers and the Deposit Bank. The
Deposit Account shall be under the sole dominion and control of Lender (which
dominion and control may be exercised by Servicer). Among other things, the
Deposit Account Agreement shall provide that the Borrowers shall have no access
to or control over the Deposit Account, that all available funds on deposit in
the Deposit Account shall be transferred by wire transfer (or transfer via the
ACH System) on each Business Day by the Deposit Bank into the Lock Box Account,
for application in accordance with the Cash Management Agreement. The Deposit
Bank and the Lock Box Account Bank shall be directed to deliver to the Borrowers
copies of bank statements and other information made available by the Deposit
Bank and the Lock Box Account Bank concerning the Deposit Account and the Lock
Box Account, respectively.

            (ii) Each Tenant occupying space at the Properties shall be, or has
been, instructed, by irrevocable written direction, in form and substance
reasonably acceptable to Lender, to pay all Rents and other amounts owed to
Borrower directly to the Deposit Account, unless Lender shall otherwise direct
in writing. The Borrowers shall, or shall cause Manager to, send direction
letters to each Tenant until each such Tenant commences paying all required
amounts to the Deposit Account, and, if any Tenant ceases to pay such amounts to
the Deposit Account for three (3) consecutive months, shall send additional
direction letters to the applicable Tenant, until such Tenant complies with such
irrevocable written directions. The Borrowers shall cause any and all other
Receipts to be deposited promptly into the Deposit Account and in no event later
than two (2) Business Days after receipt thereof by the Borrowers or Manager. To
the extent that the Borrowers or any Person on their behalf holds any Receipts,
whether in accordance with this Loan Agreement or otherwise, the Borrowers shall
be deemed to hold the same in trust for Lender for the protection of the
interests of Lender hereunder and under the Loan Documents.

            (iii) The Borrowers shall pay all reasonable out-of-pocket costs and
expenses incurred by Lender in connection with the transactions and other
matters contemplated by this Section 7.1, including but not limited to, Lender's
reasonable attorneys' fees and expenses, and all reasonable fees and expenses of
the Deposit Bank and the Lock Box Account Bank, including without limitation
their reasonable attorneys' fees and expenses.

                                       62

        (B) LOCK BOX ACCOUNT. On or before the Closing Date, pursuant to the
terms of the Cash Management Agreement, an Eligible Account shall be established
in the name of Lender, as secured party hereunder, to serve as the "Lock Box
Account" (said account, and any account replacing the same in accordance with
this Loan Agreement and the Cash Management Agreement, the "LOCK BOX ACCOUNT";
and the depositary institution in which the Lock Box Account is maintained, the
"LOCK BOX ACCOUNT BANK"). The Lock Box Account shall be under the sole dominion
and control of Lender (which dominion and control may be exercised by Servicer);
and except as expressly provided hereunder and/or in the Cash Management
Agreement, the Borrowers shall not have the right to control or direct the
investment or payment of funds therein during the continuance of an Event of
Default. Lender may elect to change any financial institution in which the Lock
Box Account shall be maintained if such institution is no longer an Eligible
Bank, upon not less than five (5) Business Days' notice to the Borrower. The
Lock Box Account shall be deemed to contain such sub-accounts as Lender may
designate ("SUB-ACCOUNTS"), which may be maintained as separate ledger accounts
and need not be separate Eligible Accounts. The Sub-Accounts shall include the
following as more particularly described in the Cash Management Agreement:

            (i) "DEBT SERVICE SUB-ACCOUNT" shall mean the Sub-Account of the
Lock Box Account established for the purposes of reserving for payments of
principal and interest and other amounts due under the Loan Documents (but
without duplication of amounts covered under item (ii) below); and

            (ii) "RESERVE SUB-ACCOUNTS" shall mean the Sub-Accounts of the Lock
Box Account established for the purpose of holding funds in the Reserves
including: (a) the "Imposition and Insurance Reserve Sub-Account", (b) the "Cash
Trap Reserve Sub-Account", (c) the "Advance Rents Reserve Sub-Account", and (d)
the "Loss Proceeds Reserve SubAccount".

SECTION 7.2 APPLICATION OF FUNDS IN LOCK BOX ACCOUNT. Funds in the Lock Box
Account shall be allocated to the Sub-Accounts or the other Accounts (or paid,
as the case may be) in accordance with the Cash Management Agreement.

SECTION 7.3 APPLICATION OF FUNDS AFTER EVENT OF DEFAULT. If any Event of Default
shall occur and be continuing, then notwithstanding anything to the contrary in
this Section or elsewhere, Lender shall have all rights and remedies available
under applicable law and under the Loan Documents. Without limitation of the
foregoing, for so long as an Event of Default exists, Lender may apply any and
all Receipts in the Deposit Account, the Lock Box Account, the Cash Trap Reserve
Sub-Account and any other Accounts or Sub-Accounts against all or any portion of
any of the Obligations, in any order.

other Loan Documents (whether such amount is interest, principal, Reserves, or
otherwise), or to pay for any Insurance Policies required pursuant to Section
5.4 hereof; or

        (B) OTHER PAYMENTS. Failure of the Borrowers to pay any amount from time
to time owing under this Loan Agreement, the Note, or any other Loan Documents

        (D) BREACH OF PROVISIONS REGARDING INSURANCE, TRANSFERS, LIENS, SINGLE
PURPOSE. Breach or default under any of Section 5.4, 5.10, 5.15, 5.16, 5.17,
5.18, Article IX (including with respect to Manager or Guarantor), or Section
11.1 (provided that in the case of an involuntary Lien under Section 5.16 or
11.1, the same shall not constitute an Event of Default if such liens, in the
aggregate, are not reasonably likely to have a Material Adverse Effect or if
within thirty (30) days after the Borrowers' receipt of notice thereof, the
Borrowers shall either (i) cause the same to be removed of record, or (ii)
provide to Lender security for the same in an amount and pursuant to terms both
satisfactory to Lender in Lender's sole discretion); provided however that if
(x) the default under Sections 5.10, 5.16 or 11.1 is capable of cure but with
diligence cannot be cured within such period of thirty (30) days, (y) the
Borrowers (or the applicable Borrower Party) has commenced the cure within such
thirty (30) day period and has pursued such cure diligently, and (z) each

of the foregoing, then such period shall be extended for so long as is
reasonably necessary for the Borrowers in the exercise of due diligence to cure
such default, but in no event beyond ninety (90) days after the original notice
of default); or

        (E) BREACH OF WARRANTY. Any representation, warranty, certification or
other statement made by any Borrower, Guarantor or Manager in any Loan Document
or in any statement or certificate at any time given in writing pursuant to or
in connection with any Loan Document is false as of the date made and such
breach is reasonably likely to have a Material Adverse Effect, provided that
such breach shall not constitute an Event of Default if within fortyfive (45)
days of the Borrowers' Knowledge thereof (or such longer period as may be
consented to by Lender), the Borrowers' take such action as may be required to
make such representation, warranty, certification or other statement to be true
as made, which may include removing the affected Property by effectuating a
Release, Substitution or Other Property Substitution subject to the terms of
Section 11.4, Section 11.5 or Section 11.6, respectively; or

        (F) OTHER DEFAULTS UNDER LOAN DOCUMENTS. A default shall occur in the

Material Adverse Effect and such default is not fully cured within thirty (30)
days after receipt by the Borrowers of written notice from Lender of such
default; provided however that if (i) the default is capable of cure but with
diligence

                                       64

cannot be cured within such period of thirty (30) days, (ii) the Borrowers (or

day period and has pursued such cure diligently, and (iii) each Borrower
delivers to Lender promptly following written demand (which demand may be made
from time to time by Lender) evidence reasonably satisfactory to Lender of the
foregoing, then such period shall be extended for so long as is reasonably
necessary for the Borrowers in the exercise of due diligence to cure such
default, but in no event beyond one hundred and twenty (120) days after the
original notice of default; or

        (G) INVOLUNTARY BANKRUPTCY; APPOINTMENT OF RECEIVER, ETC. (i) A court
enters a decree or order for relief with respect to any Borrower Party in an
Involuntary Borrower Bankruptcy, or Manager in a proceeding under the Bankruptcy
Code or under applicable bankruptcy, insolvency or other similar law where
Manager is a debtor, which decree or order is not stayed or other similar relief
is not granted under any applicable federal or state law unless dismissed within
ninety (90) days; (ii) the occurrence and continuance of any of the following
events for ninety (90) days unless dismissed or discharged within such time: (x)
an Involuntary Borrower Bankruptcy is commenced, (y) a decree or order of a

part of the property of such Person; or

        (H) VOLUNTARY BANKRUPTCY; APPOINTMENT OF RECEIVER, ETC. (i) An order for
relief is entered with respect to any Borrower Party or Manager, or any Borrower
Party or Manager commences a voluntary case under the Bankruptcy Code or any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consents to the entry of an order for relief in an involuntary case
or to the conversion of an involuntary case to a voluntary case under any such

as described in either of Subsections 8.1(G) or 8.1(H), all or any portion of
the Collateral (other than Ground Leased Properties for which the Ground Lessor
is the subject of a bankruptcy proceeding) becomes property of the estate or
subject to the automatic stay in any case or proceeding under the Bankruptcy
Code or any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect (provided that if the same occurs in the context of an
involuntary proceeding, it shall not constitute an Event of Default if it is
dismissed or discharged within ninety (90) days following its occurrence); or

        (J) SOLVENCY. Any Borrower Party or Manager ceases to be solvent or
admits in writing its present or prospective inability to pay its debts as they
become due; or

                                       65

        (K) JUDGMENT AND ATTACHMENTS. Any lien, money judgment, writ or warrant
of attachment, or similar process is entered or filed against any Borrower Party

        (L) INJUNCTION. The Borrowers are enjoined, restrained or in any way
prevented by the order of any court or any administrative or regulatory agency

the Borrowers or any Lien securing the Obligations shall, in whole or in part,
cease to be a perfected first priority Lien, subject to the Permitted
Encumbrances (except in any of the foregoing cases in accordance with the terms
hereof or under any other Loan Document) which is reasonably likely to have a
Material Adverse Effect, and the Borrowers do not take all actions requested by
Lender to correct such defect within ten (10) days after the written request by
Lender to take such action, or any Person under the control of the Borrowers or
Guarantor who is a party thereto, other than Lender, denies that it has any
further liability (as distinguished from denial of the existence of a Default or
Event of Default) under any Loan Documents to which it is party, or gives notice
to such effect; or

        (N) INTENTIONALLY OMITTED; or

        (O) DEFAULT UNDER MANAGEMENT AGREEMENT. Any breach or default shall
occur in the material obligations of the Borrowers under the Management
Agreement, and such breach or default either is of such a nature or continues
for such a period of time beyond applicable notice and cure periods, if any,
that Manager shall have the right to exercise material remedies as a consequence
thereof; or

        (P) GROUND LEASE. Any default by any of the Borrowers beyond any
applicable grace period shall occur under any Ground Lease and the Borrowers
have not effectuated a Release or Substitution of such affected Property within
forty-five (45) days of the expiration of such grace period or, subject to
Section 5.23 or Section 11.5 hereof, any actual or attempted surrender,
termination, modification or amendment of any Ground Lease without Lender's
prior written consent; or

        (Q) EASEMENTS. Any default by any of the Borrowers beyond any applicable
grace period shall occur under any Easement and the Borrowers have not
effectuated a Release or Substitution of such affected Property within

written consent.

        (R) INDEBTEDNESS OF GSI. Any breach of, or default under, Section 5.25.

                                       66

            If more than one of the foregoing paragraphs shall describe the same
condition or event, then Lender shall have the right to select which paragraph
or paragraphs shall apply. In any such case, Lender shall have the right (but
not the obligation) to designate the paragraph or paragraphs which provide for
non-written notice (or for no notice) or for a shorter time to cure (or for no
time to cure).

SECTION 8.2 ACCELERATION AND REMEDIES.

        (A) Upon the occurrence and during the continuance of any Event of
Default described in any of Subsections 8.1(G), 8.1(H), or 8.1(I), the unpaid
principal amount of and accrued interest and fees on the Loan and all other
Obligations shall automatically become immediately due and payable, without
presentment, demand, protest, notice of intent to accelerate, notice of
acceleration or other requirements of any kind, all of which are hereby
expressly waived by the Borrowers. Upon and at any time after the occurrence of
any other Event of Default, at the option of Lender, which may be exercised
without notice or demand to anyone, all or any portion of the Loan and other
Obligations shall immediately become due and payable.

        (B) Upon the occurrence and during the continuance of an Event of
Default, all or any one or more of the rights, powers, privileges and other
remedies available to Lender against the Borrowers under this Loan Agreement
(including Article X hereof) or any of the other Loan Documents, or at law or in
equity, may be exercised by Lender at any time and from time to time, whether or
not all or any of the Obligations shall be declared due and payable, and whether
or not Lender shall have commenced any foreclosure proceeding or other action
for the enforcement of its rights and remedies under any of the Loan Documents
with respect to the Properties. Any such actions taken by Lender shall be
cumulative and concurrent and may be pursued independently, singly,
successively, together or otherwise, at such time and in such order as Lender
may determine in its sole discretion, to the fullest extent permitted by law,
without impairing or otherwise affecting the other rights and remedies of Lender
permitted by law, equity or contract or as set forth herein or in the other Loan
Documents. Without limiting the generality of the foregoing, if an Event of
Default is continuing (i) to the fullest extent permitted by law, Lender shall
not be subject to any "one action" or "election of remedies" law or rule, and
(ii) all liens and other rights, remedies or privileges provided to Lender shall
remain in full force and effect until Lender has exhausted all of its remedies
against each Property and the Deeds of Trust have been foreclosed, sold and/or
otherwise realized upon in satisfaction of the Obligations or the Obligations
have been paid in full.

        (C) Lender shall have the right from time to time to partially foreclose
the Deeds of Trust in any manner and for any amounts secured by the Deeds of
Trust then due and payable as determined by Lender in its sole discretion
including, without limitation, the following circumstances: (i) in the event the
Borrowers default beyond any applicable grace period in the payment of one or
more scheduled payments of principal and interest, Lender may foreclose the Deed
of Trust to recover such delinquent payments, or (ii) in the event Lender elects
to accelerate less than the entire outstanding principal balance of the Loan,
Lender may foreclose the Deed of Trust or any of them to recover so much of the
principal balance of the Loan as Lender may accelerate and such other sums
secured by the Deed of Trust as Lender may elect.

                                       67

Notwithstanding one or more partial foreclosures, the Property shall remain
subject to the Deed of Trust to secure payment of sums secured by the Deed of
Trust and not previously recovered.

        (D) During the continuance of an Event of Default, Lender shall have the
right from time to time to sever the Note and the other Loan Documents into one
or more separate notes, mortgages and other security documents in such
denominations as Lender shall determine in its sole discretion for purposes of
evidencing and enforcing its rights and remedies provided hereunder. The
Borrowers shall execute and deliver to Lender from time to time, within ten (10)
days after the request of Lender, a severance agreement and such other documents
as Lender shall reasonably request in order to effect the severance described in
the preceding sentence, all in form and substance reasonably satisfactory to
Lender. The Borrowers hereby absolutely and irrevocably appoint Lender as their
true and lawful attorney, coupled with an interest, in their name and stead to
make and execute all documents reasonably necessary to effect the aforesaid
severance if the Borrowers fail to do so within ten (10) days of Lender's
written request, the Borrowers ratifying all that their said attorney shall do
by virtue thereof.

        (E) Any amounts recovered from the Properties or any other collateral
for the Loan after an Event of Default may be applied by Lender toward the
payment of any interest and/or principal of the Loan and/or any other amounts
due under the Loan Documents in such order, priority and proportions as Lender
in its sole discretion shall determine.

        (F) The rights, powers and remedies of Lender under this Loan Agreement
shall be cumulative and not exclusive of any other right, power or remedy which
Lender may have against the Borrowers pursuant to this Loan Agreement or the
other Loan Documents, or existing at law or in equity or otherwise. Lender's
rights, powers and remedies may be pursued singly, concurrently or otherwise, at
such time and in such order as Lender may determine in Lender's sole discretion.
No delay or omission to exercise any remedy, right or power accruing upon an
Event of Default shall impair any such remedy, right or power or shall be
construed as a waiver thereof, but any such remedy, right or power may be
exercised from time to time and as often as may be deemed expedient. A waiver of
one Default or Event of Default with respect to the Borrowers shall not be
construed to be a waiver of any subsequent Default or Event of Default by the
Borrowers or to impair any remedy, right or power consequent thereon.

SECTION 8.3 PERFORMANCE BY LENDER.

        (A) Upon the occurrence and during the continuance of an Event of
Default, if any of the Borrowers shall fail to perform, or cause to be
performed, any material covenant, duty or agreement contained in any of the Loan
Documents (subject to applicable notice and cure periods), Lender may perform or
attempt to perform such covenant, duty or agreement on behalf of the Borrowers
including making protective advances on behalf of any Borrower, or, in its sole
discretion, causing the obligations of any of the Borrowers to be satisfied with
the proceeds of any Reserve. In such event, the Borrowers shall, at the request
of Lender, promptly pay to Lender, or reimburse, as applicable, any of the
Reserves, any actual amount reasonably expended or disbursed by Lender in such
performance or attempted performance, together with interest thereon at the
Default Rate (including reimbursement of any applicable Reserves), from the date
of such expenditure or disbursement, until paid. Any amounts advanced or
expended by Lender to perform or attempt to perform any such matter shall be
added to and included within the

                                       68

indebtedness evidenced by the applicable Note and shall be secured by all of the
Collateral securing the applicable Loan. Notwithstanding the foregoing, it is
expressly agreed that Lender shall not have any liability or responsibility for
the performance of any obligation of the Borrowers under this Loan Agreement or
any other Loan Document, and it is further expressly agreed that no such
performance by Lender shall cure any Event of Default hereunder.

        (B) Lender may cease or suspend any and all performance required of
Lender under the Loan Documents upon and at any time after the occurrence and
during the continuance of any Event of Default.

SECTION 8.4 EVIDENCE OF COMPLIANCE. Promptly following request by Lender, each
Borrower shall provide such documents and instruments as shall be reasonably
satisfactory to Lender to evidence compliance with any material provision of the
Loan Documents applicable to the Borrowers.

of the Obligations hereunder and under the Note and the other Loan Documents.
The Other Company Collateral is subject to the security interest in favor of
Lender created herein and all provisions of this Loan Agreement and the other
Loan Documents. The Borrowers hereby authorize Lender to file such financing
statements as Lender shall deem reasonably necessary to perfect Lender's
interest in the Other Company Collateral. Upon the occurrence and during the
continuance of any Event of Default, Lender shall have all rights and remedies
pertaining to the Other Company Collateral as are provided for in any of the
Loan Documents or under any applicable law. Without limitation of Lender's
rights of enforcement with respect to the Other Company Collateral or any part
thereof, Lender may exercise its rights of enforcement with respect to the Other
Company Collateral or any part thereof under the UCC as amended (or under the
UCC in force in any other state to the extent the same is applicable law) and in
conjunction with, in addition to, or in substitution for, those rights and
remedies:

of, assemble and collect the Other Company Collateral or to render it unusable.

            (ii) Lender may require the Borrowers to assemble the Other Company

convenient to allow Lender to take possession or dispose of the Other Company
Collateral.

            (iii) Written notice mailed to the Borrowers as provided herein at
least five (5) days prior to the date of public sale of the Other Company
Collateral or prior to the date after which private sale of the Other Company
Collateral will be made shall constitute reasonable notice.

            (iv) In the event of a foreclosure sale, the Other Company
Collateral and the other Properties may, at the option of Lender, be sold as a
whole.

            (v) It shall not be necessary that Lender take possession of the
Other Company Collateral or any part thereof prior to the time that any sale
pursuant to the provisions of this section is conducted and it shall not be
necessary that the Other Company Collateral or any part thereof be present at
the location of such sale.

            (vi) Prior to application of proceeds of disposition of the Other
Company Collateral to the secured indebtedness, such proceeds shall be applied
to the reasonable expenses of retaking, holding, preparing for sale or lease,
selling, leasing and the like and the reasonable attorneys' fees and legal
expenses incurred by Lender.

            (vii) Any and all statements of fact or other recitals made in any
bill of sale or assignment or other instrument evidencing any foreclosure sale
hereunder as to nonpayment of the secured indebtedness or as to the occurrence
of any default, or as to Lender having declared all of such indebtedness to be
due and payable, or as to notice of time, place and terms of sale and of the
properties to be sold having been duly given, or as to any other act or thing
having been duly done by Lender, shall be taken as prima facie evidence of the
truth of the facts so stated and recited.

            (viii) Lender may appoint or delegate any one or more persons as
agent to perform any act or acts necessary or incident to any sale held by
Lender, including the sending of notices and the conduct of the sale, but in the
name and on behalf of Lender.

irrespective of the number of tiers of ownership without Lender's consent and
receipt of a Rating Confirmation.

such proposed transferee and its Affiliates owned in the aggregate (directly or
indirectly) forty-nine percent (49%) or less of such interests in Guarantor or
Manager, as applicable); and, provided that such Transfer shall not be a
Permitted Ownership Interest Transfer unless Lender receives, prior to such
Transfer, both (x) evidence reasonably satisfactory to Lender (which shall
include a legal non-consolidation opinion reasonably acceptable to Lender and
the Rating Agencies) that the single purpose nature and bankruptcy remoteness of
the Borrowers, the Guarantor or Manager, as applicable (and their members and
general partners, as applicable) following such Transfer or Transfers will be
the same as prior to such Transfer or Transfers and (y) Rating Confirmation.

        (C) A Transfer in connection with an initial public offering ("IPO") of
shares in any entity either directly or indirectly controlling Guarantor or
Manager will be permitted at any time, provided that following such IPO the
shares of such entity are listed on any recognized stock exchange.

Guarantor and/or the Manager as part of a formation of an UPREIT, DownREIT, or
similar operating partnership structure, pursuant to which some or all of the
direct and indirect subsidiaries of GSI, including the Guarantor and/or the
Manager, may be held through a subsidiary partnership or limited liability
company that is treated for federal income tax purposes as a partnership or a
disregarded entity controlled at least 51% as to profits and capital by GSI, and
which may include the conversion of any of the Borrowers that are structured as
corporations into limited liability companies or similar entities that may be
treated as partnerships or disregarded entities for federal income tax purposes;
provided that such Transfer will not be permitted unless Lender receives, prior
to such Transfer, both (x) evidence reasonably satisfactory to Lender (which

acceptable to Lender and the Rating Agencies) that the single purpose nature and
bankruptcy remoteness of the Guarantor, the Manager and the Borrowers (and their
members and general partners, as applicable) following such Transfer or
Transfers will be the same as prior to such Transfer or Transfers and (y) Rating
Confirmation.

        For purposes of this Section 11.2, "control" shall have the meaning
given thereto in the definition of "Affiliate" in Section 1.1 and a "change of
control" of any Person shall include the

                                       74

Transfer of legal or equitable ownership interests in such Person which after
giving effect to such Transfer results in any transferee or pledgee of such
interests holding more than a 49% legal or equitable ownership interest or
security interest in such Person.

SECTION 11.3 DEFEASANCE. Prior to the Anticipated Repayment Date, the Borrowers
may defease the Loan at any time, in whole or, from time to time, in part, as of
the last day of an Interest Accrual Period, in accordance with the following
provisions:

        (A) Lender shall have received from the Borrowers not less than thirty

        (B) The Borrowers shall also pay to Lender all interest due through and
including the last day of the Interest Accrual Period applicable to the Payment
Date on which such defeasance is being made, together with any and all other
amounts due and owing pursuant to the terms of the Loan Documents, including,
without limitation, any costs incurred in connection with a defeasance.

        (C) No Event of Default shall have occurred and be continuing unless, in
connection with such defeasance, the Release of one or more Properties which are
the subject of a proposed defeasance will cure such Event of Default.

        (D) The Borrowers shall (i) deliver Federal Obligations sufficient to
make the Scheduled Defeasance Payments to Lender (ii) deliver to Lender (1) a
security agreement, in form and substance reasonably satisfactory to Lender,
creating a first priority lien on the Federal Obligations purchased by Borrowers

priority perfected security interest in the Federal Obligations; (4) if only a
portion of the Loan is being defeased, the Borrowers shall execute and deliver
all necessary documents to split the Note into two substitute notes, one having
a principal balance equal to the defeased portion of the Note (the "DEFEASED
NOTE") and one note having a principal balance equal to the undefeased portion
of the Note (the "UNDEFEASED NOTE"), the amortization schedule for which notes
shall be calculated to fully amortize the respective principal balances of each
on a twenty-five (25) year schedule (commencing on the Closing Date) and with a

appropriate document, shall authorize and direct that the payments received from
the Federal Obligations shall be made directly to Lender and applied to satisfy
the obligations of the Borrowers under the Defeased Note. The Defeased Note and
the Undefeased Note shall have identical terms as the Note, except for the
principal balance, payment amounts and amortization schedules and with a balloon
payment on the Defeased Note due on the

                                       75

Anticipated Repayment Date which shall be appropriately adjusted to reflect the
defeasance. A Defeased Note cannot be the subject of a further defeasance.

        (E) Lender shall have received a Rating Confirmation.

        (F) If the Borrowers defease the Loan in whole and will continue to own
any assets other than the Federal Obligations delivered to Lender, the Borrowers

entity reasonably acceptable to Lender (the "SUCCESSOR BORROWERS"), with respect
to which a substantive nonconsolidation opinion satisfactory to Lender has been
delivered to Lender and the Borrowers shall transfer and assign to the Successor
Borrowers all obligations, rights and duties under the Note and the Security
Agreement, together with the pledged Federal Obligations. The Successor
Borrowers shall assume the obligations of the Borrowers under the Note and the
Security Agreement and the Borrowers shall be relieved of its obligations
hereunder and thereunder. The Borrowers shall pay Ten and No/100 Dollars

obligations.

SECTION 11.4 RELEASE OF PROPERTIES. If (x) the Borrowers defease all or a
portion of the Loan pursuant to Section 11.3 hereof to facilitate the

shall, promptly upon satisfaction of all the following terms and conditions
execute, acknowledge and deliver to the Borrowers a release of applicable Loan
Documents with respect to any such Property (a "RELEASE", and each such released
Property, a "RELEASED PROPERTY") in recordable form with respect to the
applicable Released Property:

        (A) In the event of a prepayment of the Loan in part, but not in whole,
Lender shall have received the Release Price on the date proposed for such
prepayment, which shall be applied in accordance with Section 2.4(A) hereof.

        (B) Except for prepayments or defeasances, as applicable, which are made
contemporaneously with the application of Loss Proceeds towards the payment of
the Loan where such Loss Proceeds constitute at least fifty percent (50%) of the
Release Price, Lender shall have received from the Borrowers evidence in form
and substance satisfactory to Lender that the Debt Service Coverage Ratio
immediately following the Release is equal to the greater of (x) 1.45:1 or (y)
the Debt Service Coverage Ratio immediately prior to effecting such Release
(unless the Borrowers have delivered a Rating Confirmation in connection with
such Release), accompanied by an Officer's Certificate stating that the
statements, calculations and information comprising such evidence are true,
correct and complete in all respects.

        (C) The Borrowers shall, at their sole expense, prepare any and all
documents and instruments necessary to effect the Release, all of which shall be
subject to the reasonable approval of Lender, and the Borrowers shall pay all
costs reasonably incurred by Lender (including, but not limited to, reasonable
attorneys' fees and disbursements, title search costs or endorsement premiums)
in connection with the review, execution and delivery of the Release.

        (D) No Event of Default has occurred and is continuing, unless the
proposed Release will cure such Event of Default.

                                       76

        (E) Immediately following such Release, the Released Property will be
owned by a Person other than the Borrowers or any of their Affiliates (unless
such Release is effectuated to cure a Default, in which event the Released
Property may be owned by an Affiliate of the Borrowers).

Notwithstanding the foregoing to the contrary, following the Anticipated
Repayment Date, the Borrowers may request a Release of one or more Properties
subject to (i) Lender's prior approval, (ii) payment of a release price
satisfactory to Lender, and (iii) delivery of a Rating Confirmation.

SECTION 11.5 SUBSTITUTION OF PROPERTY. Prior to the Anticipated Repayment Date,
subject to the terms and conditions set forth in this Section 11.5, the
Borrowers shall have the right to obtain a release of the lien of the applicable
Deed of Trust (and the related Loan Documents) encumbering a Mortgaged Property
(for purposes of this section only, hereinafter referred to as, the "SUBSTITUTED
PROPERTY") by (i) substituting therefor one or more properties of like kind and
quality (which shall include, among other things, the geographic diversity of
the Substituted Property and markets and submarkets with, among other
similarities, similar demographics, populations, absorption trends,
accessibility and visibility) acquired by the applicable Borrower or (ii), with
respect to any of the Ground Leased Properties, subjecting the fee interest, or
an easement interest, in such Ground Leased Property to the lien of a security
instrument in favor of Lender as security for the Loan (individually, a
"REPLACEMENT PROPERTY" and collectively, the "REPLACEMENT PROPERTIES"). In
addition, any such substitution (each a "SUBSTITUTION") shall be subject, in
each case, to the satisfaction of the following conditions precedent:

        (A) No Event of Default shall have occurred and be continuing, unless
the release of the Substituted Property will cure such Event of Default.

        (B) The Borrowers shall have given Lender at least forty-five (45) days
prior written notice of its election to seek a Substitution.

        (C) The value of the Replacement Property, as established by the
Borrowers to the reasonable satisfaction of Lender, shall be at least equal to
the value of the Substituted Property as of the date immediately preceding the
Substitution.

        (D) After giving effect to the Substitution, the Debt Service Coverage
Ratio of the Loan is at least equal to the Debt Service Coverage Ratio of the
Loan as of the date immediately preceding the Substitution.

        (E) Lender shall have received a copy of the instrument conveying to the
applicable Borrower the transferred interests and, if such instrument creates a
leasehold interest or an easement interest in favor of the Borrowers, such
instrument shall be reasonably satisfactory to Lender, contain such Lender
protections as are contained in similar instruments accepted by Lender at
Closing, and is accompanied by an estoppel or similar instrument reasonably
satisfactory to Lender.

        (F) The Borrowers shall have executed, acknowledged and delivered to
Lender (i) a mortgage, a deed of trust, or a deed to secure debt, as applicable,
with respect to the Replacement Property, so as to effectively create upon
recording and filing valid and enforceable liens upon

                                       77

the Replacement Property, of first priority, in favor of Lender (or such other
trustee as may be desired under local law), subject only to the Permitted
Encumbrances and such other liens as are permitted pursuant to the Loan
Documents, (ii) an environmental indemnity with respect to the Replacement
Property, (iii) written confirmation from each Guarantor regarding such
Substitution, (iv) modifications to the Loan Documents as Lender deems desirable
to properly reflect the Substitution, and (vi) such other documents and
agreements as reasonably requested to evidence the Substitution. The security
instrument and environmental indemnity shall be in the same form and substance
as the counterparts of such documents executed and delivered with respect to the
Substituted Property, subject to modifications reflecting the Replacement
Property as the property that is the subject of such documents and such
modifications reflecting the laws of the State in which the Replacement Property
is located.

        (G) Lender shall have received (i) a title insurance policy (or a
marked, signed and redated commitment to issue such title insurance policy)
reasonably satisfactory to Lender insuring the lien of the security instrument
encumbering the Replacement Property, issued by the Title Company and dated as
of the date of the Substitution, and (ii) reasonably requested endorsements to
the title policies delivered to Lender in connection with the Deeds of Trust to
reflect the Substitution. Lender also shall have received copies of paid
receipts showing that all premiums in respect of such endorsements and title
insurance policies have been paid.

        (H) The Borrowers shall deliver or cause to be delivered to Lender (i)
updates certified by the Borrowers of all organizational documentation related
to the Borrowers and/or the formation, structure, existence, good standing
and/or qualification to do business delivered to Lender in connection with the
Closing; (ii) good standing certificates, certificates of qualification to do
business in the State in which the Replacement Property is located (if required
in such State) and (iii) resolutions, if any are required, authorizing the
Substitution and any actions taken in connection with such Substitution.

        (I) Lender shall have received such opinions as may be reasonably
requested with respect to the Loan Documents delivered with respect to the
Replacement Property, the Borrower's qualification, and authorization
substantially in the form delivered at Closing, together with an update of the
insolvency opinion indicating that the Substitution does not affect the opinions
set forth therein, and an opinion of counsel stating that the Substitution does
not constitute a "significant modification" of the Loan or "deemed exchange" of
the Note under Section 1001 of the Code.

        (J) Lender shall have received a Rating Confirmation.

        (K) The Borrowers shall have paid or reimbursed Lender for all third
party out-ofpocket costs and expenses incurred by Lender (including, without

                                  ARTICLE XIII
                 WAIVERS OF DEFENSES OF GUARANTORS AND SURETIES

SECTION 13.1 WAIVERS. To the extent that any of the Borrowers (in this Article,
a "WAIVING PARTY") is deemed for any reason to be a guarantor or surety of or
for any other Borrower Party or Affiliate or to have rights or obligations in
the nature of the rights or obligations of a guarantor or surety (whether by
reason of execution of a guaranty, provision of security for the obligations of
another, or otherwise) then this Article shall apply. This Article shall not
affect the rights of the Waiving Party other than to waive or limit rights and
defenses that Waiving Party would have (i) in its capacity as a guarantor or
surety or (ii) in its capacity as one having rights or obligations in the nature
of a guarantor or surety.

        Waiving Party hereby waives diligence, presentment, demand of payment,
filing of claims with a court in the event of receivership or bankruptcy of any
of the other Borrower Parties, protest or notice with respect to any of the
obligations of any of the other Borrower Parties, setoffs and counterclaims and
all presentments, demands for performance, notices of nonperformance, protests,
notices of protest, notices of dishonor and notices of acceptance, the

                                       82

benefits of all statutes of limitation, and all other demands whatsoever (and
shall not require that the same be made on any of the other Borrower Parties as
a condition precedent to the obligations of Waiving Party), and covenants that
the Loan Documents will not be discharged, except by complete payment and
performance of the obligations evidenced and secured thereby, except only as
limited by the express contractual provisions of the Loan Documents. Waiving
Party further waives all notices that the principal amount, or any portion
thereof, and/or any interest on any instrument or document evidencing all or any
part of the obligations of any of the other Borrower Parties to Lender is due,
notices of any and all proceedings to collect from any of the other Borrower
Parties or any endorser or any other guarantor of all or any part of their
obligations, or from any other person or entity, and, to the extent permitted by
law, notices of exchange, sale, surrender or other handling of any security or
collateral given to Lender to secure payment of all or any part of the
obligations of any of the other Borrower Parties.

        Except only to the extent provided otherwise in the express contractual
provisions of the Loan Documents, Waiving Party hereby agrees that all of its
obligations under the Loan Documents shall remain in full force and effect,
without defense, offset or counterclaim of any kind, notwithstanding that any
right of Waiving Party against any of the other Borrower Parties or defense of
Waiving Party against Lender may be impaired, destroyed, or otherwise affected
by reason of any action or inaction on the part of Lender. Waiving Party waives
all rights and defenses arising out of an election of remedies by the Lender,
even though that election of remedies, may have destroyed the Waiving Party's
rights of subrogation and reimbursement against the other Borrower Parties.

        Lender is hereby authorized, without notice or demand, from time to
time, (a) to renew, extend, accelerate or otherwise change the time for payment
of, or other terms relating to, all or any part of the obligations of any of the
other Borrower Parties; (b) to accept partial payments on all or any part of the
obligations of any of the other Borrower Parties; (c) to take and hold security
or collateral for the payment of all or any part of the obligations of any of
the other Borrower Parties; (d) to exchange, enforce, waive and release any such
security or collateral for such obligations; (e) to apply such security or
collateral and direct the order or manner of sale thereof as in its discretion
it may determine; (f) to settle, release, exchange, enforce, waive, compromise
or collect or otherwise liquidate all or any part of such obligations and any
security or collateral for such obligations. Any of the foregoing may be done in
any manner, and Waiving Party agrees that the same shall not affect or impair
the obligations of Waiving Party under the Loan Documents.

        Waiving Party hereby assumes responsibility for keeping itself informed
of the financial condition of all of the other Borrower Parties and any and all
endorsers and/or other guarantors of all or any part of the obligations of the
other Borrower Parties, and of all other circumstances bearing upon the risk of
nonpayment of such obligations, and Waiving Party hereby agrees that Lender
shall have no duty to advise Waiving Party of information known to it regarding
such condition or any such circumstances.

        Waiving Party agrees that neither Lender nor any person or entity acting
for or on behalf of Lender shall be under any obligation to marshal any assets
in favor of Waiving Party or against or in payment of any or all of the
obligations secured hereby. Waiving Party further agrees that, to the extent
that any of the other Borrower Parties or any other guarantor of all or

                                       83

any part of the obligations of the other Borrower Parties makes a payment or
payments to Lender, or Lender receives any proceeds of collateral for any of the
obligations of the other Borrower Parties, which payment or payments or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside and/or required to be repaid or refunded, then, to the extent of such
payment or repayment, the part of such obligations which has been paid, reduced
or satisfied by such amount shall be reinstated and continued in full force and
effect as of the time immediately preceding such initial payment, reduction or
satisfaction.

        Waiving Party (i) shall have no right of subrogation with respect to the
obligations of the other Borrower Parties; (ii) waives any right to enforce any
remedy that Lender now has or may hereafter have against any of the other
Borrower Parties any endorser or any guarantor of all or any part of such
obligations or any other person; and (iii) waives any benefit of, and any right
to participate in, any security or collateral given to Lender to secure the
payment or performance of all or any part of such obligations or any other
liability of the other parties to Lender.

        Waiving Party agrees that any and all claims that it may have against
any of the other Borrower Parties, any endorser or any other guarantor of all or
any part of the obligations of the other Borrower Parties, or against any of
their respective properties, shall be subordinate and subject in right of
payment to the prior payment in full of all obligations secured hereby.
Notwithstanding any right of any of the Waiving Party to ask, demand, sue for,
take or receive any payment from the other Borrower Parties, all rights, liens
and security interests of Waiving Party, whether now or hereafter arising and
howsoever existing, in any assets of any of the other Borrower Parties (whether
constituting part of the security or collateral given to Lender to secure
payment of all or any part of the obligations of the other Borrower Parties or
otherwise) shall be and hereby are subordinated to the rights of Lender in those
assets.

                                       84

THE OBLIGATIONS ARISING HEREUNDER AND THEREUNDER SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
CONTRACTS MADE AND PERFORMED IN THE STATE OF NEW YORK AND ANY APPLICABLE LAWS OF
THE UNITED STATES OF AMERICA EXCEPT THAT AT ALL TIMES THE PROVISIONS FOR THE
CREATION, PERFECTION AND ENFORCEMENT OF THE LIENS AND SECURITY INTERESTS CREATED
PURSUANT TO THE DEED OF TRUST AND THE ASSIGNMENT OF LEASES SHALL BE GOVERNED BY
THE LAWS OF THE STATE WHERE THE PROPERTY IS LOCATED, EXCEPT THAT THE SECURITY
INTERESTS IN ACCOUNT COLLATERAL SHALL BE GOVERNED BY THE LAWS OF THE STATE OF
NEW YORK OR THE STATE WHERE THE SAME IS HELD, AT THE OPTION OF LENDER.

SECTION 14.12 SUCCESSORS AND ASSIGNS. This Loan Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns except that the Borrowers may not assign their rights or obligations
hereunder or under any of the other Loan Documents except as expressly provided
in Article XI.

                                       88

SECTION 14.13 SOPHISTICATED PARTIES, REASONABLE TERMS, NO FIDUCIARY
RELATIONSHIP. The Borrowers, on behalf of themselves and all Borrower Parties,
represent, warrant and acknowledge that (i) they are sophisticated real estate
investors, familiar with transactions of this kind, and (ii) they have entered
into this Loan Agreement and the other Loan Documents after conducting their own
assessment of the alternatives available to them in the market, and after
lengthy negotiations in which they have been represented by legal counsel of
their choice. The Borrowers, on behalf of themselves and all Borrower Parties,
also acknowledge and agree that the rights of Lender under this Loan Agreement
and the other Loan Documents are reasonable and appropriate, taking into
consideration all of the facts and circumstances including without limitation
the quantity of the Loan, the nature of the Properties, and the risks incurred
by Lender in this transaction. No provision in this Loan Agreement or in any of
the other Loan Documents and no course of dealing between the parties shall be
deemed to create (i) any partnership or joint venture between Lender and the
Borrowers or any other Person, or (ii) any fiduciary or similar duty by Lender
to the Borrowers or any other Person. The relationship between Lender and the
Borrowers is exclusively the relationship of a creditor and a debtor, and all
relationships between Lender and any other Borrower are ancillary to such
creditor/debtor relationship.

SECTION 14.14 REASONABLENESS OF DETERMINATIONS. In any instance where any
consent, approval, determination or other action by Lender is, pursuant to the
Loan Documents or applicable law, required to be done reasonably or required not
to be unreasonably withheld, then Lender's action shall be presumed to be
reasonable, and the Borrowers shall bear the burden of proof of showing that the
same was not reasonable. In the event that a claim or adjudication is made that
Lender or its agents have acted unreasonably or unreasonably delayed acting in
any case where, by law or under this Loan Agreement or the other Loan Documents,
Lender or such agent, as the case may be, has an obligation to act reasonably or
promptly, neither Lender nor its agents shall be liable for any monetary
damages, and the Borrowers' sole remedy shall be limited to commencing an action
seeking injunctive relief or declaratory judgment. Any action or proceeding to
determine whether Lender has acted reasonably shall be determined by an action
seeking declaratory judgment.

SECTION 14.15 LIMITATION OF LIABILITY. Neither Lender, nor any Affiliate,
officer, director, employee, attorney, or agent of Lender, shall have any
liability with respect to, and each of the Borrowers hereby waives, releases,
and agrees not to sue any of them upon, any claim for any special, indirect,
incidental, or consequential damages suffered or incurred by the Borrower
Parties in connection with, arising out of, or in any way related to, this Loan
Agreement or any of the other Loan Documents, or any of the transactions
contemplated by this Loan Agreement or any of the other Loan Documents, other
than the gross negligence or willful misconduct of Lender. Each of the Borrowers
hereby waives, releases, and agrees not to sue Lender or any of Lender's
Affiliates, officers, directors, employees, attorneys, or agents for punitive
damages in respect of any claim in connection with, arising out of, or in any
way related to, this Loan Agreement or any of the other Loan Documents, or any
of the transactions contemplated by this Loan Agreement or any of the
transactions contemplated hereby, except to the extent the same is caused by the
gross negligence or willful misconduct of Lender.

SECTION 14.16 NO DUTY. All attorneys, accountants, appraisers, and other
professional Persons and consultants retained by Lender shall have the right to
act exclusively in the interest of Lender

                                       89

and shall have no duty of disclosure, duty of loyalty, duty of care, or other
duty or obligation of any type or nature whatsoever to any of the Borrowers or
Affiliates thereof, or any other Person.

SECTION 14.17 ENTIRE AGREEMENT. This Loan Agreement, the Note, and the other
Loan Documents referred to herein embody the final, entire agreement among the
parties hereto and supersede any and all prior commitments, agreements,
representations, and understandings, whether written or oral, relating to the
subject matter hereof and may not be contradicted or varied by evidence of
prior, contemporaneous, or subsequent oral agreements or discussions of the
parties hereto. There are no oral agreements among the parties to the Loan
Documents.

SECTION 14.18 CONSTRUCTION; SUPREMACY OF LOAN AGREEMENT. The Borrowers and
Lender acknowledge that each of them has had the benefit of legal counsel of its
own choice and has been afforded an opportunity to review this Loan Agreement
and the other Loan Documents with its legal counsel and that this Loan Agreement
and the other Loan Documents shall be construed as if jointly drafted by the
Borrowers and Lender. If any term, condition or provision of this Loan Agreement
shall be inconsistent with any term, condition or provision of any other Loan
Document, then this Loan Agreement shall control.

SECTION 14.19 CONSENT TO JURISDICTION. EACH OF THE BORROWERS HEREBY CONSENTS TO
THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE COUNTY OF NEW
YORK, STATE OF NEW YORK OR WITHIN THE COUNTY AND STATE IN WHICH THE PROPERTY IS
LOCATED AND IRREVOCABLY AGREES THAT, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS SHALL BE LITIGATED IN
SUCH COURTS. EACH OF THE BORROWERS ACCEPTS FOR ITSELF AND IN CONNECTION WITH THE
PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS, AND IRREVOCABLY
AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS
AGREEMENT, THE NOTE, SUCH OTHER LOAN DOCUMENTS OR SUCH OBLIGATION. NOTHING
HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY
LAW OR SHALL LIMIT THE RIGHT OF LENDER TO BRING PROCEEDINGS AGAINST ANY BORROWER
IN THE COURTS OF ANY OTHER JURISDICTION.

SECTION 14.20 WAIVER OF JURY TRIAL. EACH OF THE BORROWERS AND LENDER HEREBY
WAIVES ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF THIS LOAN AGREEMENT, ANY OF THE LOAN DOCUMENTS, OR
ANY DEALINGS BETWEEN ANY BORROWER PARTY AND LENDER RELATING TO THE SUBJECT
MATTER OF THIS LOAN TRANSACTION AND THE LENDER/BORROWER RELATIONSHIP THAT IS
BEING ESTABLISHED. EACH OF THE BORROWER PARTIES AND LENDER ALSO WAIVES ANY BOND
OR SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE
REQUIRED OF IT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF
ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE

                                       90

TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING WITHOUT LIMITATION,
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW
AND STATUTORY CLAIMS. EACH OF THE BORROWERS AND LENDER ACKNOWLEDGES THAT THIS
WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO THIS LOAN AGREEMENT, THAT EACH HAS
ALREADY RELIED ON THE WAIVER IN ENTERING INTO THIS LOAN AGREEMENT AND THAT EACH
WILL CONTINUE TO RELY ON THE WAIVER IN THE FUTURE. EACH OF THE BORROWERS AND
LENDER FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS
LEGAL COUNSEL, AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL
RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE,
MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS
TO THIS LOAN AGREEMENT, THE LOAN DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR
AGREEMENT RELATING TO THE LOAN. IN THE EVENT OF LITIGATION, THIS LOAN AGREEMENT
MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

SECTION 14.21 COUNTERPARTS; EFFECTIVENESS. This Loan Agreement and other Loan
Documents and any amendments or supplements thereto may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed an original, but
all of which counterparts together shall constitute but one and the same
instrument. This Loan Agreement shall become effective upon the execution of a
counterpart hereof by each of the parties hereto.

SECTION 14.22 SERVICER. Lender shall have the right from time to time to
designate and appoint a Servicer and special servicer, and to change or replace
any Servicer or special servicer. Provided that the Borrowers have been notified
of such Servicer's role, all rights of the Lender hereunder may be exercised by
Servicer on behalf of Lender. Lender shall notify the Borrowers in writing as to
the identity of the Servicer and any special servicer.

SECTION 14.23 OBLIGATIONS OF BORROWER PARTIES. The Borrower Parties other than
the Borrowers are parties to this Loan Agreement only with regard to the
representations, warranties, and covenants specifically applicable to them.

SECTION 14.24 ADDITIONAL INSPECTIONS; REPORTS. Notwithstanding anything
contained in this Loan Agreement to the contrary, if for any reason whatsoever
Lender suspects that any conditions exist or may exist at any Property which
might have a Material Adverse Effect, Lender shall have the right, at the
Borrowers' sole reasonable cost and expense, to cause such inspections and
reports to be prepared and performed with respect to any Property as Lender
shall reasonably determine.

SECTION 14.25 CROSS-DEFAULT; CROSS-COLLATERALIZATION; WAIVER OF MARSHALLING OF
ASSETS.

        (A) Each of the Borrowers acknowledges that Lender has made the Loan to
each of the Borrowers upon the security of the Properties and the Other Company
Collateral and in

                                       91

reliance upon the aggregate value of the Properties and the Other Company
Collateral taken together being of greater value as collateral security than the
sum of each such Property and each of the Borrowers' interests in the Company
Collateral taken separately. Each of the Borrowers agrees that the Deeds of
Trusts and other security agreements given hereunder are and will be
cross-collateralized and cross-defaulted with each other so that (i) an Event of
Default shall constitute an Event of Default under each of the Deeds of Trusts
and the other security agreements given hereunder which secure the Note; (ii)
each Deed of Trust and the other security agreements given hereunder shall
constitute security for the Note as if a single blanket lien were placed on all
of the Properties and the Other Company Collateral as security for the Note; and
(iv) such cross-collateralization shall in no event be deemed to constitute a
fraudulent conveyance.

        (B) To the fullest extent permitted by law, each of the Borrowers, for
itself and its successors and assigns, waives all rights to a marshalling of the
assets of each of the Borrowers, each of the Borrower's members and others with
interests in each of the Borrowers, and of the Properties and the Other Company
Collateral, or to a sale in inverse order of alienation in the event of
foreclosure of all or any of the Deeds of Trusts or the Other Company
Collateral, and agrees not to assert any right under any laws pertaining to the
marshalling of assets, the sale in inverse order of alienation, homestead
exemption, the administration of estates of decedents, or any other matters
whatsoever to defeat, reduce or affect the right of Lender under the Loan
Documents to a sale of the Properties and the Other Company Collateral for the
collection of the Loan without any prior or different resort for collection or
of the right of Lender to the payment of the Loan out of the net proceeds of the
Properties and the Other Company Collateral in preference to every other
claimant whatsoever. In addition, each of the Borrowers, for itself and its
successors and assigns, waives in the event of foreclosure of any or all of the
Deeds of Trusts or Other Company Collateral, any equitable right otherwise
available to each of the Borrowers which would require the separate sale of the
Properties and the Other Company Collateral or require Lender to exhaust its
remedies against any such Properties and the Other Company Collateral or any
combination of the Properties and the Other Company Collateral before proceeding
against any other Properties and the Other Company Collateral or combination of
Properties and the Other Company Collateral; and further in the event of such
foreclosure each of the Borrowers does hereby expressly consent to and
authorize, at the option of Lender, the foreclosure and sale either separately
or together of any combination of the Properties and the Other Company
Collateral.
