(1)  As of the cut-off date, the weighted average life, principal window and
     assumed final distribution date were calculated assuming no prepayments
     will be made on the mortgage loans prior to their related maturity dates
     and the other assumptions set forth under "YIELD AND MATURITY
     CONSIDERATIONS - Yield Considerations" in the prospectus supplement.

(2)  Not offered hereby. Any information provided in this term sheet regarding

     these holders are entitled to receive payments of the aggregate interest
     accrued on the notional amount of each of the components of the class X-P
     and class X-C certificates as described in the prospectus supplement. The
     interest rate applicable to each component of the class X-P and class X-C

     D, class E, class F, class G, class H, class J, class K, class L, class M,
     class N, class O, and class P certificates will equal one of (i) a fixed
     rate, (ii) the weighted average of the net interest rates on the mortgage
     loans (in each case, adjusted if necessary to accrue on the basis of a
     360-day year consisting of twelve 30-day months) as of their respective due
     dates in the month preceding the month in which the related distribution
     date occurs, (iii) a rate equal to the lesser of a specified pass-through
     rate and the rate specified in clause (ii) or (iv) the rate specified in
     clause (ii) less a specified percentage.

                              equal to the product of (a) the amount of the
                              prepayment premiums or yield maintenance charges
                              net of workout fees and liquidation fees ,
                              multiplied by (b) a fraction, the numerator of
                              which is equal to the excess, if any, of the
                              pass-through rate for that class of certificates
                              over the relevant discount rate, and the
                              denominator of which is equal to the excess, if
                              any, of the mortgage interest rate of the prepaid
                              mortgage loan over the relevant discount rate,
                              multiplied by (c) a fraction, the numerator of
                              which is equal to the amount of principal payable
                              to that class of certificates on that payment
                              date, and the denominator of which is the Total
                              Principal Payment Amount for that payment date.

                              The portion, if any, of the prepayment premiums or
                              yield maintenance charges remaining after any
                              payments described above will be distributed 100%
                              to the holders of the class X-C certificates.

ADVANCES                      The master servicer and, if it fails to do so, the
                              trustee will be obligated to make P&I advances and
                              servicing advances, including paying delinquent
                              property taxes and insurance premiums, but only to
                              the extent that those advances are not deemed
                              non-recoverable and in the case of P&I advances
                              subject to any appraisal reductions that may
                              occur.

APPRAISAL REDUCTIONS          An appraisal reduction generally will be created
                              in the amount, if any, by which the principal
                              balance of a required appraisal loan (plus other
                              amounts overdue or advanced in connection with
                              such loan) exceeds 90% of the appraised value of
                              the related mortgaged property plus certain
                              escrows and reserves (including letters of credit)
                              held with respect to the mortgage loan. As a
                              result of calculating an appraisal reduction
                              amount for a given mortgage loan, the interest
                              portion of any P&I advance for such loan will be
                              reduced, which will have the effect of reducing
                              the amount of interest available for distribution
                              to the certificates in reverse alphabetical order
                              of the classes. A required appraisal loan will
                              cease to be a required appraisal loan when the
                              related mortgage loan has been brought current for
                              at least three consecutive months and no other
                              circumstances exist, which would cause such
                              mortgage loan to be a required appraisal loan.

OPTIONAL TERMINATION          The master servicer, the special servicer and
                              certain certificateholders will have the option to
                              terminate the trust, in whole but not in part, and
                              purchase the remaining assets of the trust on or
                              after the payment date on which the stated
                              principal balance of the mortgage loans then
                              outstanding is less than 1.0% of the initial
                              mortgage pool balance. The purchase price will
                              generally be at a price equal to the unpaid
                              aggregate principal balance of the mortgage loans
                              (or fair market value in the case of REO
                              Properties), plus accrued and unpaid interest and
                              certain other additional trust fund expenses, as
                              described in the prospectus supplement. In
                              addition, after the certificate balance of the
                              class A-1 through class E certificates has been
                              reduced to zero, the trust may also be terminated,
                              subject to the consent of the master servicer (in
                              its sole discretion), if all of the remaining
                              series 2005-GG4 certificates (excluding class R
                              and class LR) are held by a single
                              certificateholder, and that certificateholder
                              exchanges all of the then outstanding series
                              2005-GG4 certificates (excluding class R and class
                              LR) for the mortgage loans remaining in the trust.

CONTROLLING CLASS             The class of sequential pay certificates (a) which
                              bears the latest alphabetical class designation
                              (other than the class X-P, class X-C, class R and
                              class LR certificates) and (b) which has a
                              certificate balance greater than 25% of its
                              original certificate balance; provided, however,
                              that if no class of sequential pay certificates
                              satisfies clause (b) above, the controlling class
                              will be the outstanding class of sequential pay
                              certificates bearing the latest alphabetical class
                              designation (other than the class X-P, class X-C,
                              class R and class LR certificates); provided,
                              further, with respect to certain issues related to
                              the mortgage loans that are part of a split
                              structure, the holder of the majority interest of
                              the related subordinated or pari passu companion
                              loan may have certain consultation or approval
                              rights with respect to servicing matters, as
                              described in the prospectus supplement.

TENANTS                       References in this term sheet to the rating of a
                              tenant may refer to the rating of a parent of the
                              actual tenant and the rated entity may not be an
                              actual party to that lease. The rated parent may
                              not guarantee the lease.

ERISA                         The offered certificates are expected to be ERISA
                              eligible.

SMMEA                         The class A-1, class A-2, class A-3, class A-AB,
                              class A-4, class A-J, class B and class C
                              certificates are expected to be "mortgage-related
                              securities" for the purposes of SMMEA so long as
                              they remain rated in one of the two highest rating
                              categories by a nationally recognized statistical
                              rating organization.

which back the certificates is insured or guaranteed by any governmental agency
or instrumentality or by any private mortgage insurer or by The Royal Bank of
Scotland plc, the depositor, the underwriters, the mortgage loan sellers, the
master servicer, the special servicer, or any other party.

o    THE LOAN. The mortgage loan (the "MALL AT WELLINGTON GREEN LOAN") was
     initially evidenced by a single note in the aggregate original principal
     amount of $200,000,000 and is secured by a first mortgage encumbering a
     super-regional shopping mall located at 10300 West Forest Hill Boulevard,
     Wellington, Florida (the "MALL AT WELLINGTON GREEN Property"). The Mall at
     Wellington Green Loan was originated on May 12, 2005 by Archon Financial,
     L.P. and was subsequently purchased by Goldman Sachs Mortgage Company, and

     guarantor of the non-recourse carve-outs and an indemnitor of certain
     environmental obligations under the Mall at Wellington Green Loan. The
     Taubman Realty Group Limited Partnership has also guaranteed the payment of
     certain amounts which may become payable by the borrower to Nordstrom
     pursuant to Nordstrom's lease, which provides that the landlord thereunder
     shall, if Nordstrom's gross sales are below certain threshold amounts for
     any of the first four lease years, pay to Nordstrom certain specified
     percentages of the difference between Nordstrom's actual gross sales and
     certain threshold gross sales amounts or, in certain cases, a fixed sum set
     forth in Nordstrom's lease, up to $1.875 million per annum for each of the
     first four lease years. This obligation is currently scheduled to expire in
     2007.

o    ESCROWS. At origination, the borrower deposited $5,357,410 into a reserve
     for unfunded obligations, which amounts will be disbursed by the lender
     pursuant to borrower's request that such amounts are due under the
     applicable lease. The loan documents also provide for certain escrows of
     real estate taxes and insurance, tenant improvements and leasing
     commissions (in a maximum amount equal to $1,209,350) and capital
     expenditures (in a maximum amount equal to $186,068) to be funded during a
     Mall at Wellington Green Lockbox Period. A "MALL AT WELLINGTON GREEN

     income of the Mall at Wellington Green Property for the four calendar
     fiscal quarters most recently ended is less than $13,200,000 as of the end
     of any calendar quarter until the net operating income of the Mall at
     Wellington Green Property for the four calendar fiscal quarters most
     recently ended is at least equal to $13,200,000 as of the end of two
     consecutive calendar quarters.

o    LOCKBOX AND CASH MANAGEMENT. The Mall at Wellington Green Loan requires a
     hard lockbox, which is already in place. The loan documents require the
     borrower to direct the tenants to pay their rents directly to a
     lender-controlled lockbox account, except that the loan documents permit
     the borrower to maintain a separate account (the "MALL AT

     Mall at Wellington Green Property and other miscellaneous revenue from
     sources other than regular tenants at the Mall at Wellington Green Property
     may be deposited. No withdrawals are permitted from the Mall at Wellington
     Green Kiosk Account and on any business day on which the amount on deposit
     in the Mall at Wellington Green Kiosk Account exceeds $100,000 (or, during
     a Mall at Wellington Green Lockbox Period, $50,000), such excess funds are
     required to be transferred into the lender-controlled lockbox account. The
     loan documents also require that all rents received by the borrower or the
     property manager be deposited into the lockbox account within one business
     day after receipt. On each business day that no Mall at Wellington Green
     Lockbox Period exists, provided no event of default is continuing under the
     Mall at Wellington Green Loan, all funds in the lockbox account will be
     remitted to an account specified by the borrower. During the continuance of
     a Mall at Wellington Green Lockbox Period, provided no event of default is
     continuing under the Mall at Wellington Green Loan, funds in the lockbox
     account will be applied on each payment date and on the last business day
     of each week to pay the monthly debt service, fund any required reserves
     under the loan documents and pay all other amounts then due to lender and
     any remaining funds will be released to the borrower. During the

     the lender may apply any funds in the lockbox account to the obligations of
     the borrower under the Mall at Wellington Green Loan in such order of
     priority as the lender may determine.

o    PROPERTY MANAGEMENT. The Mall at Wellington Green Property is currently
     managed by The Taubman Company LLC, an affiliate of the borrower, pursuant
     to a management agreement. The property manager of the Mall at Wellington
     Green Property is currently entitled to (i) a base management fee in an
     amount equal to 5% of all income derived by the borrower from the Mall at
     Wellington Green Property and (ii) for each lease executed by the borrower
     for space at the Mall at Wellington Green Property, a leasing commission in
     an amount equal to 5% of the product of (x) the average minimum annual rent
     for the term of such lease and (y) the number of years in the term of such
     lease, provided that the leasing commission will not exceed 30% of the
     average minimum annual rent for the term of such lease. In addition, the
     property manager of the Mall at Wellington Green Property is entitled to
     additional compensation for certain other services provided pursuant to the
     management agreement. Under the loan documents, the Mall at Wellington
     Green Property may be managed by a reputable and experienced management
     organization possessing experience in managing properties similar in size,
     scope and value as the Mall at Wellington Green Property for whom each
     rating agency has confirmed in writing that the management of the Mall at
     Wellington Green Property by such entity will not cause the downgrade,
     withdrawal or qualification of the then current ratings of any class of the
     series 2005-GG4 certificates. The lender may require the borrower to
     replace the property manager if an event of default under the Mall at
     Wellington Green Loan has occurred and the lender has accelerated the loan
     or if the property manager becomes insolvent.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. Not Permitted.

o    TERRORISM INSURANCE. The Mall at Wellington Green Loan documents require
     that the commercial property and business income insurance policies
     required to be maintained by the borrower provide coverage for perils and
     acts of terrorism in an amount equal to (i) 100% of the full replacement
     cost of the Mall at Wellington Green Property and (ii) 100% of the
     projected gross rental income from the Mall at Wellington Green Property on
     an actual loss sustained basis, from the date of the casualty to the date
     that the Mall at Wellington Green Property is repaired or restored and an
     extended period of indemnity endorsement for the succeeding 12-month period
     after the completion of such repair or restoration. The borrower is only
     required to maintain such amount of terrorism coverage as may be obtained
     at a cost equal to (x) $175,000 for the first four years after the one-year
     anniversary of the origination of the loan and (y) $225,000 for the
     remainder of the term of the loan. In addition, the borrower is permitted
     to maintain such terrorism coverage through a blanket policy with a
     deductible not in excess of $500,000 or such higher deductible if the
     borrower delivers to the lender a letter of credit in an amount equal to
     the difference between the actual deductible and $500,000. The letter of
     credit may be drawn upon by the lender upon the occurrence of a casualty to
     pay such amounts that would have been paid by the issuer of the insurance
     policy if the actual deductible had been $500,000. See "Risk
     Factors--Property Insurance" and "--Risks Associated with Blanket Insurance
     Policies" in the prospectus supplement.

o    THE LOAN. The mortgage loan (the "WELLS FARGO CENTER TRUST LOAN") is
     evidenced by a single note and is secured by a first mortgage encumbering
     the class-A office building located at 1700 Lincoln Street, Denver,
     Colorado (the "WELLS FARGO CENTER PROPERTY"). The Wells Fargo Center Trust
     Loan represents approximately 5.0% of the initial mortgage pool balance.

     original principal balance and a principal balance as of the cut-off date
     of $200,000,000, and an interest rate of 5.257% per annum. The proceeds of
     the Wells Fargo Center Trust Loan, together with the Wells Fargo Companion
     Loan (as described below), were used to acquire the Wells Fargo Center
     Property.

     The Wells Fargo Center Trust Loan is a pari passu portion of a whole
     mortgage loan with an original principal balance of $276,000,000. The

     separate pari passu note with an interest rate of 5.257% per annum and a

     Fargo Center Companion Loan (collectively, the "WELLS FARGO CENTER LOAN
     GROUP") are governed by a co-lender agreement, as described in the
     prospectus supplement under "Description of the Mortgage Pool--The Whole
     Loans" and will be serviced pursuant to the terms of the 2005-GG4 pooling
     and servicing agreement.

     The IP DSCR, UW DSCR and LTV on the Wells Fargo Center Loan Group are
     1.31x, 1.54x and 80.0%, respectively.

     The Wells Fargo Center Trust Loan has an initial term of 120 months and a
     remaining term of 118 months. The loan requires payments of interest only
     for the entire term. The scheduled maturity date is April 6, 2015.
     Voluntary prepayment of the Wells Fargo Center Trust Loan is prohibited
     prior to the payment date of January 6, 2015 and permitted on such payment
     date and thereafter without penalty. Defeasance with United States
     government securities or certain other obligations backed by the full faith

     52-story office building located at 1700 Lincoln Street in Denver,
     Colorado. Built by Hines Corporation in 1982, the Wells Fargo Center

     system. The Wells Fargo Center Property has an adjacent 12-level parking
     garage with a total of 996 parking spaces and 9,292 square feet of retail
     space, which is part of the collateral.

     million square feet of property. MPI now owns a portfolio totaling
     approximately 24.9 million square feet comprised of 23 office properties
     (58 buildings) with approximately 14.8 million square feet of NRA, one
     350-room hotel and parking structure of approximately 9.8 million square
     feet. MPI also owns undeveloped land that can support up to 5.0 million
     square feet of office, retail and residential uses. In 1965, Robert F.
     Maguire III founded MPI's predecessor, Maguire Partners, to own, manage,
     develop and acquire office properties in the Southern California market.
     Over its 38-year history, Maguire Partners established a successful record
     of developing visible class-A buildings. MPI is one of the largest
     commercial real estate developers and owners headquartered on the West
     Coast and one of the nation's largest developers of class-A quality office
     and mixed-use properties. The company specializes in large, architecturally
     significant projects, and has developed a number of significant projects in
     Los Angeles County, including Wells Fargo Tower, US Bank Tower, Gas Company
     Tower, and KPMG Tower. MPLP guaranteed the non-recourse carveouts of the
     Wells Fargo Center Trust Loan. MPLP has master leased 60,000 square feet of
     the Wells Fargo Center Property expiring March 15, 2008. The borrower under
     the Wells Fargo Center Trust Loan is affiliated with the borrowers under
     the mortgage loans identified on Annex C-1 to the prospectus supplement as
     Lantana Campus, 700 N. Central Avenue and 801 N. Brand Avenue. See "Risk
     Factors--Risks Relating to Loan Concentrations" in the prospectus
     supplement.

o    ESCROWS. The loan documents provide for certain escrows of real estate
     taxes and insurance premiums. At closing, the borrower deposited $282,187
     into a deferred maintenance reserve for the payment of short term or
     immediate required repairs at the Wells Fargo Center Property. At closing,
     the borrower deposited $3,700,000 for then-outstanding tenant improvements
     and leasing commissions. At closing, the borrower also deposited funds into
     a rent holdback reserve in the amount of $4,593,605 to simulate the full
     unabated base rent payments for certain leases for the term of the Wells
     Fargo Center Loan. Additionally, at closing, the borrower deposited
     $400,000 in a WFB reserve as security in connection with the alleged
     overcharges of "additional rent" asserted by WFB.

o    LOCKBOX AND CASH MANAGEMENT. The loan requires a hard lockbox, which is
     already in place. The loan documents require the borrower to direct tenants
     to pay their rents directly to a lender-controlled hard lockbox. The loan
     documents also require that all rents received by the borrower or the
     property manager be deposited into the lender-controlled account (as well
     as any other rents, receipts, security deposits or payments related to
     lease termination or default) within one business day of receipt and that
     funds deposited in the lender-controlled account be swept on a daily basis
     into the borrower's operating account unless an event of default is
     continuing or the debt service coverage ratio is less than 1.10x (a "DSCR
     CASH MANAGEMENT PERIOD"). If an event of default is continuing or during a
     DSCR Cash Management Period, amounts in the lender-controlled account will
     be swept into another account controlled by lender and applied to pay debt
     service, operating expenses and any required reserves under the loan
     documents. At any time during the continuance of an event of default,
     lender may apply any sums then held pursuant to the cash management
     agreement to the payment of the debt. Additionally, if a DSCR Cash
     Management Period is continuing for two consecutive calendar quarters,
     lender may use the additional cash collateral to purchase defeasance
     eligible collateral and apply the proceeds of such collateral to pay a
     portion of the monthly payments due under the Wells Fargo Center Loan Group
     each month.

o    PROPERTY MANAGEMENT. MPLP, an affiliate of the borrower, is the property
     manager for the Wells Fargo Center Property. The lender may replace the
     property manager if (i) an event of default occurs and not cured, (ii) a
     bankruptcy of MPLP occurs, (iii) the maturity date has occurred and the
     loan is not repaid or (iv) the property manager defaults under the property
     management agreement. Thereafter, the borrower may not enter into any
     agreement relating to the management of the property with any party without
     the express written consent of lender and the rating agencies. The
     management fee is equal to 3.0% of all rent and other income collected from
     tenants at the Wells Fargo Center Property. Leasing commissions are payable
     separately based on a fixed schedule. MPLP contracts out certain services
     to an affiliated subcontractor pursuant to a services subcontract that is
     terminable by either party on 30 days' notice.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. There is currently no mezzanine or
     subordinate indebtedness. The loan documents permit MPI, MPLP or any entity
     holding any direct or indirect interests in MPI or MPLP, to pledge their
     indirect ownership interests in the borrower (but not the foreclosure
     thereon) to any permitted institutional transferee

     providing a corporate line of credit or other financing to MPI, MPLP or any
     entity holding any direct or indirect interests in MPI or MPLP, provided
     that the indirect interests in the borrower that are pledged as collateral
     comprise no more than 33% of the total value of the collateral for such
     line of credit or other financing, and provided that (i) no default has
     occurred and remains uncured and (ii) lender has received payment of, or
     reimbursement for, all costs and expenses incurred by lender in connection
     with such pledges (including, but not limited to, reasonable attorneys'
     fees and costs and expenses of the rating agencies).

o    TERRORISM INSURANCE. The loan documents require the borrower to maintain
     terrorism insurance. The Wells Fargo Center Property has terrorism coverage
     as part of its sponsor's blanket "all-risk" property coverage. The loan
     documents provide that if "certified acts of terrorism," as identified by
     the United States Government, are excluded from borrower's comprehensive
     "all-risk" insurance policy or business income coverage, the borrower is
     required to obtain an endorsement to such policies, or separate policies,
     insuring against all such "certified acts of terrorism" ("TERRORISM ACTS"),
     at the borrower's option, either (A) in an amount not less than
     $360,000,000 on an aggregate basis covering the Wells Fargo Center Property
     and all properties owned by MPLP or its affiliates as of the closing date
     of the Wells Fargo Center Loan Group and providing for a deductible not
     exceeding $1,000,000, or (B) in a total amount not less than $410,000,000
     on an aggregate basis covering the Wells Fargo Center Property and all
     properties owned by MPLP or its affiliates as of the closing date of the
     Wells Fargo Center Loan Group and providing for a deductible of not in
     excess of 5% of the full replacement value of the Wells Fargo Center
     Property (insurance meeting such requirements being referred to as "FULL
     COVERAGE"). In either case, the endorsement or policy must be (x) in form
     and substance reasonably satisfactory to lender and (y) non-cancelable (to

(1)  S&P, Moody's and Fitch have confirmed that the Streets at Southpoint Loan
     has, in the context of its inclusion in the trust, credit characteristics
     consistent with that of an obligation rated "A" by S&P, "Baa2" by Moody's
     and "A+" by Fitch.

o    THE LOAN. The mortgage loan (the "STREETS AT SOUTHPOINT LOAN") is evidenced
     by two senior notes in the aggregate original principal amount of
     $170,000,000 and is secured by a first mortgage encumbering a super
     regional shopping mall located in Durham, North Carolina (the "STREETS AT
     SOUTHPOINT PROPERTY"). The Streets at Southpoint Whole Loan was jointly
     originated one-third by Archon Financial, L.P., one-third by Commerzbank
     AG, New York Branch ("COMMERZBANK") and one-third by Teachers Insurance and
     Annuity Association of America. Goldman Sachs Mortgage Company and
     Commerzbank are the holders of the Streets at Southpoint Loan, and they are
     the joint loan sellers of the Streets at Southpoint Loan. The Streets at
     Southpoint Loan was originated on March 29, 2005 and represents
     approximately 4.2% of the initial mortgage pool balance. The proceeds from
     the Streets at Southpoint Loan were used to refinance existing debt on the
     Streets at Southpoint Property.

     The Streets at Southpoint Loan is a senior interest of a whole mortgage
     loan (the "STREETS AT SOUTHPOINT WHOLE LOAn") with an original principal
     balance of $255,000,000. The junior companion loan to the Streets at
     Southpoint Loan is evidenced by a junior note (the "STREETS AT SOUTHPOINT
     SUBORDINATE COMPANION LOAN"), with an original principal balance of
     $85,000,000 and an interest rate of 5.865%, which loan is subordinate to
     the Streets at Southpoint Loan. The Streets at Southpoint Subordinate
     Companion Loan is not an asset of the trust. Prior to an event of default,
     payments of principal and interest by the borrower are applied to the
     Streets at Southpoint Loan and the Streets at Southpoint Subordinate
     Companion Loan pro-rata based on amounts due under the respective notes.
     Each note provides for payments of interest based on the outstanding
     balance and the applicable interest rate. Payments of principal are due
     under the notes pursuant to separate amortization schedules calculated
     based on the applicable interest rate and a 360 month amortization
     schedule.

     The loans comprising the Streets at Southpoint Whole Loan are governed by
     an intercreditor agreement, as described in the prospectus supplement under
     "Description of the Mortgage Pool--The Whole Loans" and will be serviced
     pursuant to the terms of the pooling and servicing agreement. The DSCR and
     LTV on the Streets at Southpoint Loan are 1.88x and 49.9%, respectively,
     while the DSCR and LTV on the Streets at Southpoint Whole Loan are 1.22x
     and 74.8% respectively.

     The Streets at Southpoint Loan had an initial term of 84 months and has a
     remaining term of 82 months. The scheduled maturity date is the payment
     date in April 2012. Voluntary prepayment of the senior portion of the
     Streets at Southpoint Loan that is part of the trust fund is prohibited
     until the payment date in October 2011. Prepayments are permitted on the
     Streets at Southpoint Subordinate Companion Loan as described under
     "Streets at Southpoint Subordinate Companion Loan Prepayments" below.
     Defeasance with United States government securities or certain other
     obligations backed by the full faith and credit of the United States of
     America is permitted at any time after the second anniversary of the
     securitization closing date.

(1)  Calculated based on approximate square footage occupied by each tenant.

(2)  Borrower owned in-line space only.

o    THE BORROWER. The borrower is Southpoint Mall, LLC, a single-member,
     single-purpose, single-asset entity. Legal counsel to the borrower has
     delivered a non-consolidation opinion in connection with the origination of
     the Streets at Southpoint Loan. Southpoint Mall, LLC is indirectly owned by
     General Growth Properties, Inc. General Growth Properties, Inc. is a
     publicly traded real estate investment trust that owns, develops, operates
     and/or manages shopping malls in over 40 states. There is no guarantor of
     the non-recourse carve-outs under the Streets at Southpoint Loan.

o    ESCROWS. The loan documents provide for escrows of real estate taxes and
     insurance, certain tenant improvements and leasing commissions (in a
     maximum amount as of origination equal to $578,850, which amount is subject
     to change based upon the aggregate sf of all rentable area in the Streets
     at Southpoint Property) and capital expenditures (in a maximum amount, as
     of origination, equal to $115,770 which amount is subject to change based
     upon the aggregate sf of all rentable area in the Streets at Southpoint
     Property) during a Streets at Southpoint Cash Sweep Period. A "STREETS AT
     SOUTHPOINT CASH SWEEP PERIOD" means the period during the continuance of an
     event of default under the Streets at Southpoint Loan and/or if, the net
     operating income of the Streets at Southpoint Property for the prior
     twelve-month period is less than 85% of the net operating income at
     origination as of the end of any fiscal quarter until the net operating
     income of the Streets at Southpoint Property for the prior twelve-month
     period is at least equal to 85% of the net operating income at origination
     as of the end of any fiscal quarter.

o    LOCKBOX AND CASH MANAGEMENT. The Streets at Southpoint Loan requires a hard
     lockbox, which is already in place. The loan documents require the borrower
     to direct the tenants to pay their rents directly to a lender-controlled
     sweep account. The loan documents also require that all rents received by
     the borrower or the property manager be deposited into the sweep account
     within two business days after receipt. On each business day that no
     Streets at Southpoint Cash Sweep Period exists, all funds in the sweep
     account will be remitted to an account specified by the borrower. Within
     two business days of commencement of a Streets at Southpoint Cash Sweep
     Period, the borrower is required to establish a cash management account
     into which all funds in the sweep account will be remitted on each business
     day during a Streets at Southpoint Cash Sweep Period. During the existence
     of a Streets at Southpoint Cash Sweep Period, funds in the cash management
     account will be applied to pay the monthly debt service and any required
     reserves under the loan documents. Any remaining funds will be released to
     the borrower, unless an event of default is continuing, in which case, all
     available cash after the payment of the debt service and any required
     reserves will be held as additional collateral for the Streets at
     Southpoint Loan.

TEN LARGEST MORTGAGE LOANS - THE STREETS AT SOUTHPOINT
--------------------------------------------------------------------------------

o    STREETS AT SOUTHPOINT SUBORDINATE COMPANION LOAN PREPAYMENTS. Voluntary
     prepayments of the Streets at Southpoint Subordinate Companion Loan are
     permitted at any time after the second anniversary of the securitization
     closing date. The borrower is permitted to prepay the Streets at Southpoint
     Subordinate Companion Loan if the holder of the Streets at Southpoint
     Subordinate Companion Loan rejects a potential transferee of direct or
     indirect ownership interests of the borrower that would otherwise be
     permitted under the loan documents. The holder of the Streets at Southpoint
     Subordinate Companion Loan may reject a potential transferee if (i) that
     transferee or its affiliate has ever been an adverse party to the holder of
     the Streets at Southpoint Subordinate Companion Loan in any litigation or
     threatened any litigation, or (ii) that transferee or its affiliate has
     ever defaulted on a loan or on any agreement with the holder of Streets at
     Southpoint Subordinate Companion Loan that was not cured to the
     satisfaction of the holder of the Streets at Southpoint Subordinate
     Companion Loan. However, if no actual or threatened litigation or default
     is continuing, the transferee or its affiliate cannot be rejected by the
     holder of the Streets at Southpoint Subordinate Companion Loan if the
     holder of Streets at Southpoint Subordinate Companion Loan has made or
     solicited making loans to such entity or any of its affiliates subsequent
     to the events described in clauses (i) and (ii).

o    PROPERTY MANAGEMENT. The Streets at Southpoint Property is currently
     managed by Rouse Property Management, Inc., an affiliate of the borrower,
     pursuant to a management agreement. Under the loan documents, the Streets
     at Southpoint Property may be self-managed, managed by certain affiliates
     of the borrower, or managed by a manager for whom each rating agency has
     confirmed in writing will not cause the downgrade, withdrawal or
     qualification of the then current ratings of any class of the series
     2005-GG4 certificates. The lender may require the borrower to replace the
     property manager, or to cease self-managing the property, if an event of
     default under the Streets at Southpoint Loan has occurred and is
     continuing. During the continuance of a Streets at Southpoint Cash Sweep
     Period, the fees of the property manager may not exceed market rates for
     comparable properties in the geographic area.

o    RELEASE OF COLLATERAL. The borrower is permitted under the loan documents
     to obtain the release of one or more parcels or out lots that at the time
     of the proposed release are (1) "non-income" producing and (2) to be
     transferred to a third party in connection with an expansion or other
     development of the Streets at Southpoint Property subject to, among other
     things, the borrower delivering to lender (a) evidence that the release of
     the parcel will not materially diminish the value of the Streets at
     Southpoint Property as collateral for the Streets at Southpoint Loan, (b)
     an opinion of counsel that any REMIC trust that has acquired the Streets at
     Southpoint Loan will not fail to maintain its status as a REMIC solely as a
     result of the release and (c) written confirmation from each rating agency
     that the release would not cause the downgrade, withdrawal or qualification
     of the then current ratings of any class of the series 2005-GG4
     certificates. In addition, if a parcel to be released was improved as of
     the origination date of the Streets at Southpoint Loan, the consent of the
     junior lender must be obtained, and certain debt service coverage ratio and
     loan to value tests must be satisfied, prior to the release of any such
     parcel.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. The Streets at Southpoint Property
     also secures the Streets at Southpoint Subordinate Companion Loan, which is
     subordinate to the Streets at Southpoint Loan, as described in the
     prospectus supplement under "Description of the Mortgage Pool--The Whole
     Loans". In addition, the Streets at Southpoint Loan documents permit, among
     other things, (a) the pledge of direct or indirect equity interests in the
     borrower in connection with Permitted Mezzanine Debt, (b) the pledge of
     indirect interests in the borrower to secure certain inter-affiliate debt,
     (c) the pledge by certain permitted equityholders of the borrower of
     indirect interests in the borrower in connection with the pledge of all or
     substantially all of the assets of such equityholder to secure debt of such
     equityholder, and (d) the pledge of direct or indirect equity interests in
     certain permitted equityholders of the borrower, or issuance by such
     equityholders of preferred equity, or debt granting similar rights as
     preferred equity. "PERMITTED MEZZANINE DEBT" means indebtedness of a direct
     or indirect owner of the borrower that is secured by a pledge of the direct
     or indirect equity interests in the borrower; provided that, among other
     things, (i) written rating agency confirmation that such debt would not
     result in the downgrade, withdrawal or qualification of the then current
     ratings of the series 2005-GG4 certificates issued has been obtained and
     (ii) the Streets at Southpoint Property meets certain performance
     requirements specified in the Streets at Southpoint loan agreement,
     including: (A) the aggregate loan-to-value ratio of the Streets at
     Southpoint

TEN LARGEST MORTGAGE LOANS - THE STREETS AT SOUTHPOINT
--------------------------------------------------------------------------------

     Whole Loan and the mezzanine loan is not in excess of 75%, and (B) the
     aggregate debt-service-coverage-ratio of the Streets at Southpoint Whole
     Loan and the mezzanine loan for the immediately preceding twelve month
     period ending on the last day of a fiscal quarter is not less than 1.20x
     based on the actual loan constant and not less than 0.90x based on an
     assumed loan constant of 9%.

o    TERRORISM INSURANCE. The Streets at Southpoint Loan documents require that,
     during the policy year in which the loan origination occurred, the borrower
     will maintain terrorism insurance in an amount equal to 100% of the full
     replacement cost of the Streets at Southpoint Property and 100% of the
     projected annual gross rental income from the Streets at Southpoint
     Property from the date of the casualty to the date that the Streets at
     Southpoint Property is repaired or replaced and operations are resumed the
     borrower is required to maintain such coverage for an additional 60 days
     after the completion of restoration. After such policy year, the borrower
     is required to use commercially reasonable efforts, consistent with those
     of prudent owners of institutional quality commercial real estate, to
     maintain such coverage at all times while the Streets at Southpoint Loan is
     outstanding, provided such coverage is available at commercially reasonable
     rates. In the event that coverage for terrorism is not included as part of
     the "all-risk" and business income/rental-loss insurance policies, the
     borrower will be required to purchase terrorism insurance as a separate
     policy. See "Risk Factors--Property Insurance" in the prospectus
     supplement.

o    THE LOAN. The mortgage loan (the "NORTH HILLS LOAN") is evidenced by a
     single note and is secured by a first mortgage encumbering a lifestyle
     center located at 4217 Six Forks Road, Raleigh, North Carolina (the "NORTH
     HILLS PROPERTY"). The North Hills Loan represents approximately 2.6% of the
     initial mortgage pool balance. The North Hills Loan was originated on
     December 22, 2004, had an original principal balance of $105,000,000 and
     has a principal balance as of the cut-off date of $105,000,000, and an
     interest rate of 5.61%. The proceeds from the North Hills Loan were used to
     refinance existing debt on the North Hills Property.

     The North Hills Loan had an initial term of 120 months and has a remaining
     term of 115 months. The scheduled maturity date is the payment date in
     January 2015. Voluntary prepayment of the North Hills Loan is prohibited
     until the payment date in October 2014 and permitted thereafter without
     penalty. Defeasance with United States government securities or certain
     other obligations backed by the full faith and credit of the United States
     of America is permitted at any time after the second anniversary of the
     securitization closing date.

     center with two anchors and approximately 65 tenants (including a mix of
     retail and office) with a gross leasable area of 576,691 sf. The North
     Hills Property opened in 2004 and is the result of a complete redevelopment
     of a former regional mall, with the J.C. Penney store being the only
     original improvements, built in 1964. The new construction, representing
     approximately 70% of the space, took place from 2004 to 2005 along with a
     complete renovation of the J.C. Penney improvements. The North Hills
     Property is located in Wake County, North Carolina, within the
     Raleigh-Durham-Chapel Hill MSA, where the three-mile radius trade area has
     an average household income of $78,502 and a total population of 80,889.

     The North Hills Property is anchored by a 169,524 sf J.C. Penney and a
     130,130 sf Target. The Target anchor space is not part of the collateral
     securing the North Hills Loan.

TEN LARGEST MORTGAGE LOANS - NORTH HILLS
--------------------------------------------------------------------------------

     as its chairman. Since that time, the company has developed or redeveloped
     over four million sf of retail space in a variety of malls, community
     retail projects and neighborhood shopping centers. He has also leased over
     three million sf of commercial space and participated in the
     brokerage/acquisition of properties exceeding $200 million.

o    ESCROWS. The loan documents provide for the monthly escrow of real estate
     taxes and insurance in the amount of $36,204. At origination, the borrower
     deposited $70,675 into the real estate taxes and insurance reserve account.
     The loan documents also provide for the monthly collection of $4,759 for
     deposit into a replacement reserve account (unless and until such time as
     $114,226 is on deposit in such account) for replacements and repairs needed
     to be made to the North Hills Property. At origination, the borrower funded
     $5,000,000 into a reserve account for tenant improvements and leasing
     commissions ("TI/LC"). Upon depletion of that reserve, the borrower is
     required to deposit $20,000 monthly to the TI/LC reserve until the balance
     is at least $960,000. In addition, at origination, the borrower funded a
     reserve of $1,000,000 for rental concessions granted to certain tenants at
     the North Hills Property. An additional $13,636,364 was funded into an
     earnout escrow account that will be applied to prepay the North Hills Loan
     or released to the borrower as described under "-Earnout" below.

o    LOCKBOX AND CASH MANAGEMENT. The North Hills Loan requires a hard lockbox,
     which is already in place. At origination, the borrower was required to
     establish a lender-controlled sweep account. The loan documents require the
     borrower to direct the tenants to pay their rents directly to the sweep
     account. The loan documents also require that all rents received by the
     borrower or the property manager be deposited into the sweep account within
     one business day after receipt. On each business day that no (i) North
     Hills Cash Trap Period exists or (ii) event of default has occurred and is
     continuing, all funds in the sweep account will be remitted to an account
     specified by the borrower. A "NORTH HILLS CASH TRAP PERIOD" means the
     period during which the debt service coverage ratio for the prior month is
     less than 1.20x. As of the origination date of the North Hills Loan, the
     borrower has acknowledged that a North Hills Cash Trap Period exists.
     During the existence of a North Hills Cash Trap Period, funds in the cash
     management account will be applied to pay the monthly debt service,
     operating expenses and any required reserves under the loan documents and
     then released to the borrower. In addition, during the continuance of an
     event of default, all available cash after the payment of the debt service,
     operating expenses and any required reserves will be held as additional
     collateral for the North Hills Loan.

o    EARNOUT. The borrower under the North Hills Loan, at any time after April
     1, 2005 and prior to January 1, 2007, may request (up to 3 times) the
     release of amounts from the earnout escrow. Subject to the conditions set
     forth in the loan agreement, including without limitation, that no event of
     default has occurred under the North Hills Loan, an amount will be released
     from the earnout escrow such that, after the release, the loan to value
     ratio does not exceed 80% and the stressed debt service coverage ratio
     (calculated using a loan constant of 9.50%) is at least 0.90x and the
     actual debt service coverage ratio is at least 1.20x. All amounts remaining
     in the earnout release after January 1, 2007 will be applied to prepay the
     North Hills Loan as a principal prepayment and payment of an amount equal
     to the greater of 1% of the amount prepaid or a yield maintenance charge.

o    PROPERTY MANAGEMENT. The North Hills Property is managed by Kane Realty
     Corporation. Pursuant to the Management, Leasing and Development Agreement
     with respect to the North Hills Property (the "NORTH HILLS MANAGEMENT
     AGREEMENT"), Kane Realty Corporation receives (i) a management fee every
     month in an amount equal to 4% of the North Hills Property's gross
     receipts, payable in arrears, (ii) leasing commissions for each retail or
     office space leased in the North Hills Property, (iii) construction
     management and development fees (for projects in excess of $2 million), and
     (iv) other administrative fees and miscellaneous fees. The term of the
     North Hills Management Agreement is automatically renewable for one year
     and is subject to termination by either party with or without cause. The
     borrower may not terminate, cancel, modify, renew or extend the existing
     management agreement or enter into any other agreement relating to the
     management of the North Hills Property without the express consent of the
     lender.

o    RELEASE OF COLLATERAL. The borrower is permitted under the loan documents
     to obtain the release of a condominium unit utilized as a Wachovia Bank on
     January 1, 2007 upon satisfaction of certain conditions, including that (i)
     the debt service

     underwriting. UW assumes gross rental rates for the property at a "market"
     rate of $29.28 per square foot.

(2)  IP DSCR is calculated based on the interest-only debt service, net of the
     $5 million letter of credit held by lender. UW DSCR is based on the
     amortizing period debt service assuming the fully-funded loan.

o    THE LOAN. The mortgage loan (the "CENTURY CENTRE LOAN") is evidenced by a
     single note and is secured by a first mortgage encumbering the class-A
     office building located at 2601 & 2603 Main Street, Irvine, California (the

     and a principal as of the cut-off date of $100,000,000, and an interest
     rate of 5.95% per annum. The DSCR and LTV on the Century Centre Loan are
     1.15x and 73.5%, respectively. The proceeds of the Century Centre Loan were
     used to acquire the Century Centre Property.

     The Century Centre Loan has an initial term of 120 months and a remaining
     term of 116 months. The loan is interest only for the first 24 months of
     the term and amortizes thereafter based on a 360-month schedule, with
     required monthly payments of $596,339.72 beginning March 6, 2007. The
     scheduled maturity date is February 6, 2015. Voluntary prepayment of the
     Century Centre Loan is prohibited prior to the payment date of December 6,
     2014 and permitted on such payment date and thereafter without penalty.

TEN LARGEST MORTGAGE LOANS - CENTURY CENTRE OFFICE
--------------------------------------------------------------------------------

     Centre Loan. In connection with the guaranty, Olen is required to maintain
     $200 million in net worth and $50 million in liquidity. Olen was founded in
     1973 by Igor Olenicoff with a strategy to acquire and hold real estate in
     portfolio for long term appreciation. In total, Olen's holdings include 102
     properties comprising in excess of 15 million square feet and the company
     reports assets of $884 million, including real estate assets of $544
     million and liquid assets of $262 million. Olen has master leased 8,300
     square feet at the Century Centre Property expiring in January 2010. For
     additional information related to Olen, see "Risk Factors--Litigation and
     Other Matters Affecting the Mortgaged Properties or Borrowers" in the
     prospectus supplement.

o    ESCROWS. The loan documents provide for certain escrows of real estate
     taxes and insurance premiums. The loan documents require the borrower to
     make monthly payments of $7,462 for capital expenses and $37,308 per month
     for tenant improvements and leasing commissions. At closing, the borrower
     deposited $14,923 for approved capital expenses and $862,179 for then
     outstanding tenant improvements and leasing commissions.

o    LOCKBOX AND CASH MANAGEMENT. The loan requires a hard lockbox, which is
     already in place. The loan documents require the borrower to direct tenants
     to pay their rents directly to a lender-controlled hard lockbox. The loan
     documents also require that all rents received by the borrower or the
     property manager be deposited into the lender-controlled account (as well
     as any other rents, receipts, security deposits or payments related to
     lease termination or default) within one business day of receipt and that
     funds deposited in the lender-controlled account be swept on a daily basis
     into the borrower's operating account unless (i) an event of default is
     continuing, (ii) the debt service coverage ratio is less than 1.05x (a
     "DSCR CASH MANAGEMENT PERIOD"), (iii) the Ameriquest lease is 12 months
     away from expiration, (iv) the Ameriquest lease is surrendered, cancelled
     or terminated, (v) there is a default by Ameriquest under its lease, or
     (vi) Ameriquest is the subject of a bankruptcy or other insolvency
     proceeding. Upon any of (i) - (vi), all amounts in the lender-controlled
     account will be swept into an another account controlled by lender and
     applied to pay debt service, operating expenses and any required reserves
     under the loan documents. At any time during the continuance of an event of
     default, lender may apply any sums then held pursuant to the cash
     management agreement to the payment of the debt. Additionally, if a DSCR
     Cash Management Period is continuing for two consecutive calendar quarters,
     lender may use the additional cash collateral to purchase defeasance
     eligible collateral and apply the proceeds of such collateral to pay a
     portion of the monthly payments due under the Century Centre Loan each
     month.

o    PROPERTY MANAGEMENT. Realty Services Corp., a Nevada corporation, an
     affiliate of the borrower, is the property manager for the Century Centre
     Property. The lender may replace the property manager if (i) an event of
     default occurs and not cured, (ii) as of any calendar quarter, the borrower
     fails to maintain a debt service coverage ratio of at least 1.05x, (iii)
     the property manager is in default under the property management agreement,
     or (iv) upon the gross negligence, malfeasance or willful misconduct of the
     property manager. The borrower may not enter into any agreement relating to
     the management of the Century Centre Property without the express consent
     of lender and the rating agencies. The management fee is equal to 1.25% of
     all rent and other income collected from tenants.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. Not permitted.

o    TERRORISM INSURANCE. The Century Centre Property is insured against acts of
     terrorism as part of its "all-risk" property coverage. The loan documents
     require the borrower to maintain terrorism insurance in an amount equal
     100% of the full replacement cost of the Century Centre Property. There is
     no cap on the premium for terrorism insurance. See "Risk Factors--Property
     Insurance" in the Prospectus Supplement.

     been appraised for $10.6 million. After the release of the parcels, the
     resulting LTV will be 76.3%.

o    THE LOAN. The mortgage loan (the "LANTANA CAMPUS LOAN") is evidenced by a
     single note and is secured by a first mortgage encumbering the Lantana
     Entertainment Media Campus located in Santa Monica, California (the
     "LANTANA CAMPUS PROPERTY"). The Lantana Campus Loan represents
     approximately 2.4% of the initial mortgage pool balance. The Lantana Campus
     Loan was originated on December 16, 2004, had an original principal balance
     of $98,000,000 and a principal balance as of the cut-off date of
     $98,000,000, and an interest rate of 4.935% per annum. The DSCR and LTV on
     the Lantana Campus Loan are 1.90x and 70.5%, respectively. The proceeds of
     the Lantana Campus Loan were used to acquire the Lantana Campus Property.

     The Lantana Campus Loan has an initial term of 60 months and a remaining
     term of 55 months. The Lantana Campus Loan requires payments of interest
     only for the entire term. The scheduled maturity date is January 6, 2010.
     Voluntary prepayment of the Lantana Campus Loan is prohibited prior to the
     payment date of October 6, 2009 and permitted on such payment date and
     thereafter without penalty. Defeasance with United States government
     securities or certain other obligations backed by the full faith and credit
     of the United States of America is permitted from July 6, 2007.

o    THE PROPERTY. The Lantana Campus Property is a 331,974 square foot office
     campus located at 3000 West Olympic Boulevard, 2900 West Olympic Boulevard,
     3003 Exposition Boulevard, in Santa Monica, California. Constructed in
     1959-2000, the Lantana Campus Property has three separate office buildings
     and surface parking for approximately 1,392 vehicles.

     The largest tenant at the Lantana Campus Property is IMAX Corporation
     ("IMAX"), a publicly traded company on Nasdaq. IMAX occupies 20% of the
     Lantana Campus Property and 100% of the Lantana North Building. The IMAX
     lease expires in February, 2013. The second largest tenant at the Lantana
     Campus Property is JR Motion Pictures ("REVOLUTION Studios"). Revolution
     Studios occupies 18% of the Lantana Campus Property and 100% of the Lantana
     West Building. 90,812 square feet of the Lantana Campus Property is master
     leased by Lantana North Borrower (as defined herein) to Maguire Properties,
     L.P. ("MPLP"), a Maryland limited partnership and the operating partner of
     Maguire Properties, Inc, ("MPI") for a period of five years at a rental
     rate of $2,905,984 per year ($32.00 per square foot). MPLP in turn
     subleases the space to entertainment tenants for post-production and
     editing operations on a short term basis. The master lease was executed to
     help mitigate the short term leasing nature of the space over the term of
     the Lantana Campus Loan. The average occupancy for this space over the last
     four years has been 85% and the space has generated approximately $38.00
     per square foot gross of annual income, approximately 19% higher than the
     rent due under the master lease with MPLP.

     As of March 31, 2005, the Lantana Campus Property was 91.9% leased.

TEN LARGEST MORTGAGE LOANS - LANTANA CAMPUS
--------------------------------------------------------------------------------

     of class-A quality office and mixed use properties. The company specializes
     in large, architecturally significant projects, and has developed a number
     of significant projects in Los Angeles County, including Wells Fargo Tower,
     US Bank Tower, Gas Company Tower, and KPMG Tower. MPLP guaranteed the
     non-recourse carveouts of the Lantana Campus Loan. The borrowers under the
     Lantana Campus Loan are affiliated with the borrowers under the mortgage
     loans identified on Annex C-1 to the prospectus supplement as Wells Fargo
     Center, 700 N. Central Avenue and 801 N. Brand Avenue. See "Risk
     Factors--Risks Relating to Loan Concentrations" in the prospectus
     supplement.

o    RELEASE OF COLLATERAL. Under the loan documents, the borrower is permitted
     the free release of two parcels (the "RELEASE PARCELS") along portions of
     the Lantana South Property and Lantana North Property in connection with a
     future office development project. The Release Parcels were encumbered by
     the lien of the Mortgage solely because these parcels had not yet been
     legally subdivided and were not separate tax lots when the Lantana Campus
     Loan was originated. The release of the Release Parcels is subject to the
     satisfaction of certain conditions, including (i) no event of default
     exists; (ii) the borrower provides either an endorsement to the title
     insurance policy, an opinion of counsel or an architect's certificate
     indicating that each legal lot of the Release Parcels has been legally
     subdivided and conforms to zoning; and (iii) the borrower submits the form
     of reciprocal easement agreement between the borrowers and the transferee
     of the Release Parcels in form and substance satisfactory to lender in its
     reasonable discretion. The Release Parcels were attributed zero income in
     connection with the underwriting of the Lantana Campus Loan and have been
     appraised for $10.6 million. After release of the Release Parcels, the LTV
     of the Lantana Campus Loan will be 76.3%.

o    ESCROWS. The loan documents provide for certain escrows for real estate
     taxes and insurance. At closing, the borrower deposited $305,875 into a
     deferred maintenance reserve for the payment of short term or immediate
     required repairs at the Lantana Campus Property.

o    LOCKBOX AND CASH MANAGEMENT. The loan requires a hard lockbox, which is
     already in place. The loan documents require the borrower to direct tenants
     to pay their rents directly to a lender-controlled hard lockbox. The loan
     documents also require that all rents received by the borrower or the
     property manager be deposited into the lender-controlled account (as well
     as any other rents, receipts, security deposits or payments related to
     lease termination or default) within one business day of receipt and that
     funds deposited in the lender-controlled account be swept on a daily basis
     into the borrower's operating account unless an event of default is
     continuing or the debt service coverage ratio is less than 1.10x (a "DSCR
     CASH MANAGEMENT PERIOD"). If an event of default is continuing or during a
     DSCR Cash Management Period, amounts in the lender-controlled account will
     be swept into another account controlled by lender and applied to pay debt
     service, operating expenses and any required reserves under the loan
     documents. At any time during the continuance of an event of default,
     lender may apply any sums then held pursuant to the cash management
     agreement to the payment of the debt. Additionally, if a DSCR Cash
     Management Period is continuing for two consecutive calendar quarters,
     lender may use the additional cash collateral to purchase defeasance
     eligible collateral and apply the proceeds of such collateral to pay a
     portion of the monthly payments due under the Lantana Campus Loan each
     month.

o    PROPERTY MANAGEMENT. MPLP, an affiliate of the borrower, is the property
     manager for the Lantana Campus Property. The lender may replace the
     property manager if (i) an event of default occurs and is not cured, (iii)
     a bankruptcy of MPLP occurs, (iii) the maturity date has occurred and the
     loan is not repaid or (iv) the property manager defaults under the property
     management agreement. Thereafter, the borrower may not enter into any
     agreement relating to the management of the Lantana Campus Property without
     the express written consent of lender and the rating agencies. The
     management fee is equal to 3.0% of all rent and other income collected from
     tenants at the Lantana Campus Property. Leasing commissions are payable
     separately based on a fixed schedule. MPLP contracts out certain services
     to an affiliated subcontractor pursuant to a services subcontract that is
     terminable by either party on 30 days' notice.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. There is currently no mezzanine or
     subordinate indebtedness. The loan documents permit MPI, MPLP or any entity
     holding any direct or indirect interests in MPI or MPLP, to pledge their
     indirect ownership interests in the borrower (but not the foreclosure
     thereon) to any permitted institutional transferee

     providing a corporate line of credit or other financing to MPI, MPLP or any
     entity holding any direct or indirect interests in MPI or MPLP, provided
     that the indirect interests in the borrower that are pledged as collateral
     comprise no more than 33% of the total value of the collateral for such
     line of credit or other financing, and provided that (i) no default has
     occurred and remains uncured and (ii) lender has received payment of, or
     reimbursement for, all costs and expenses incurred by lender in connection
     with such pledges (including, but not limited to, reasonable attorneys'
     fees and costs and expenses of the rating agencies).

o    TERRORISM INSURANCE. The loan documents require the borrower to maintain
     terrorism insurance. The Lantana Campus Property has terrorism coverage as
     part of its sponsor's blanket "all-risk" property coverage. The loan
     documents provide that if "certified acts of terrorism," as identified by
     the United States Government, are excluded from borrower's comprehensive
     "all-risk" insurance policy or business income coverage, the borrower is
     required to obtain an endorsement to such policies, or separate policies,
     insuring against all such "certified acts of terrorism" ("TERRORISM ACTS"),
     at the borrower's option, either (A) in an amount not less than
     $300,000,000 on an aggregate basis covering the Lantana Campus Property and
     all other properties owned by MPLP or its affiliates as of the closing date
     of the Lantana Campus Loan and providing for a deductible not exceeding
     $1,000,000.00 or (B) in a total amount not less than $350,000,000 on an
     aggregate basis covering the Lantana Campus Property and all other
     properties owned by MPLP or its affiliates as of the closing date of the
     Lantana Campus Loan and providing for a deductible of not in excess of 5%
     of the full replacement value of the Lantana Campus Property; in either
     case, provided that the endorsement or policy is (x) in form and substance
     reasonably satisfactory to lender; and (y) non-cancelable (to the extent
     such non-cancelable insurance is available in the marketplace) (insurance
     meeting such requirements being referred to herein as "Full Coverage");
     provided that the borrowers will not be required to spend in excess of
     $3,000,000.00 per annum for such coverage and, in the event that Full
     Coverage is not available at a cost of $3,000,000 per annum, then the
     borrowers will be required to purchase insurance covering Terrorism Acts in
     an amount equal to the principal balance of the Lantana Campus Loan, but
     will not be required to maintain the full amount of such coverage, provided
     further that in the event that $3,000,000 is not sufficient to purchase
     coverage in an amount equal to the principal balance of the Lantana Campus
     Loan, then the borrowers will be required to obtain the greatest amount of
     coverage obtainable at a cost of $3,000,000 per annum. See "Risk
     Factors--Property Insurance" and "--Risks Associated with Blanket Insurance
     Policies" in the Prospectus Supplement.

o    THE LOAN. The mortgage loan (the "HYATT REGENCY DALLAS LOAN") is evidenced
     by a single note and is secured by a first mortgage encumbering a
     full-service, luxury hotel located at 300 Reunion Boulevard in Dallas,
     Texas (the "HYATT REGENCY DALLAS PROPERTY"). The Hyatt Regency Dallas Loan
     represents approximately 2.2% of the initial mortgage pool balance. The
     Hyatt Regency Dallas Loan was originated on December 30, 2004, had an
     original principal balance and has a principal balance as of the cut-off
     date of $90,000,000, and an interest rate of 5.59%. The Hyatt Regency
     Dallas Loan was used to refinance existing debt on the Hyatt Regency Dallas
     Property.

     The Hyatt Regency Dallas Loan is a senior interest of a whole mortgage loan
     (the "HYATT REGENCY DALLAS WHOLE LOAN") with an original principal balance
     of $110,000,000. The junior companion loan to the Hyatt Regency Dallas Loan
     is evidenced by a junior note (the "HYATT REGENCY DALLAS SUBORDINATE
     COMPANION LOAN"), with an original principal balance of $20,000,000 and an
     interest rate of 5.59%, which loan is subordinate to the Hyatt Regency
     Dallas Loan. The Hyatt Regency Dallas Subordinate Companion Loan is not an
     asset of the trust. Prior to an event of default, payments of interest by
     the borrower are applied to the Hyatt Regency Dallas Loan and the Hyatt
     Regency Dallas Subordinate Companion Loan pro-rata based on amounts due
     under the respective notes. The Hyatt Regency Dallas Whole Loan requires
     payments of interest-only for the first 24 months and then amortizes based
     on a 300-month amortization schedule. All payments of scheduled principal
     will be applied to the Hyatt Regency Dallas Subordinate Companion Loan
     prior to an event of default.

     The loans comprising the Hyatt Regency Dallas Whole Loan are governed by an
     intercreditor agreement, as described in the prospectus supplement under
     "Description of the Mortgage Pool--The Whole Loans" and will be serviced
     pursuant to the terms of the pooling and servicing agreement. The DSCR and
     LTV on the Hyatt Regency Dallas Loan are 2.73x and 52.9%, respectively,
     while the DSCR and LTV on the Hyatt Regency Dallas Whole Loan are 2.23x and
     64.7%, respectively.

     The Hyatt Regency Dallas Loan had an initial term of 120 months and has a
     remaining term of 115 months. The scheduled maturity date is the payment
     date in January 2015. Voluntary prepayment of the Hyatt Regency Dallas Loan
     is prohibited until the payment date in July 2007, then permitted subject
     to a yield maintenance charge until the payment date in October 2014. On or
     after the payment date in October 2014, prepayment is permitted on the
     Hyatt Regency Dallas Loan without penalty.

o    THE PROPERTY. The Hyatt Regency Dallas Property is a full-service,
     1,122-room luxury hotel located at the south end of the Dallas central
     business district, immediately adjacent to the Dallas Convention Center.
     The Hyatt Regency Dallas Property was originally completed and opened in
     1978, followed by an expansion in 2000 and further renovations in 2004. The
     Hyatt Regency Dallas Property's amenities include the adjacent 55-story
     Reunion Tower (including a revolving restaurant and observation deck),
     resort pool, full-service fitness facility, and 160,000 square feet of
     meeting space including three ballrooms, two exhibit halls and 56 meeting
     rooms. The Hyatt Regency Dallas Property also serves as a convention hotel
     given its proximity to the Dallas Convention Center.

       ---------------------------
       (1)   Average Daily Rate and RevPAR rounded to nearest whole dollar.

o    THE BORROWER. The borrower is Reunion Hotel, L.P., a single-asset,
     special-purpose entity. Legal counsel to the borrower delivered a
     non-consolidation opinion in connection with the origination of the Hyatt
     Regency Dallas Loan. Hunt Realty Corporation is the guarantor of the
     non-recourse carve-outs of the Hyatt Regency Dallas Loan. Hunt Realty
     Corporation was established in 1991 and serves as the centralized real
     estate investment management resource for the Hunt enterprise. Hunt Realty
     Corporation's investments are comprised of hotel and resort properties,
     luxury multifamily communities, student housing, suburban office building
     and industrial facilities, which includes Hyatt Regency DFW, DFW Freeport,
     Fossil Creek and Sharyland Plantation.

o    ESCROWS. The loan documents provide for certain escrows of real estate
     taxes and insurance during a Hyatt Regency Dallas Cash Trap Period. A
     "HYATT REGENCY DALLAS CASH TRAP PERIOD" means the period beginning on the
     last day of the fiscal quarter in which the debt service coverage ratio for
     the previous 12 months is less than 1.20x and ending on the last day of the
     next two consecutive fiscal quarters when the debt service coverage ratio
     is at least 1.20x (based on actual net cash flow and an assumed constant of
     7.43%) on the Hyatt Regency Dallas Whole Loan. During the continuance of a
     Hyatt Regency Dallas Cash Trap Period, the borrower is also required to
     deposit excess cash flow from the Hyatt Regency Dallas Property into an
     escrow account to be held as additional collateral for the Hyatt Regency
     Dallas Loan. In addition, the loan documents provide for the funding of an
     FF&E Escrow Fund in the monthly amount of 5% of the actual monthly gross
     operating revenues.

o    LOCKBOX AND CASH MANAGEMENT. The Hyatt Regency Dallas Loan requires a
     springing lockbox. After the existence of a Hyatt Regency Dallas Cash Trap
     Period or event of default, the loan documents require the borrower to
     deposit or cause to be deposited in a lender-controlled account all revenue
     received within one business day of receipt. Upon the termination of a
     Hyatt Regency Dallas Cash Trap Period and the cure of any event of default,
     the lender will direct the release of any funds in the lockbox account to
     the borrower.

o    PROPERTY MANAGEMENT. Hyatt Corporation manages the Hyatt Regency Dallas
     Property as a Hyatt Regency. The management agreement has an initial term
     of forty-three years (ending on December 31, 2029), subject to certain
     termination rights (i) as a result of certain events of default under the
     management agreement, (ii) in connection with the sale by the borrower of
     the Hyatt Regency Dallas Property to a third party and (iii) a change in
     control of the Hyatt Corporation. The management agreement provides for an
     annual management fee consisting of: (i) a basic fee equal to 1.5% of the
     Hyatt Regency Dallas Property's gross receipts for the pertinent year; (ii)
     an additional basic fee equal to the lesser of (A) 1.5% of the Hyatt
     Regency Dallas Property's gross receipts for the pertinent year, or (B) 40%
     of the Hyatt Regency Dallas Property's eligible additional basic fee profit
     (profits minus basic fee and certain debt service payments), if any, for
     that year; and (iii) an incentive fee equal to 10% of the amount (if any)
     by which the Hyatt Regency Dallas Property's eligible additional basic fee
     profit for the pertinent year exceeds the additional basic fee for that
     year. The lender may seek a replacement property manager or the immediate
     appointment of a receiver to operate and manage the Hyatt Regency Dallas
     Property if

     the property manager is terminated. The borrower may not terminate, cancel,
     materially modify, renew or extend the existing management agreement or
     enter into any other agreement relating to the management of the property
     without the express consent of the lender.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. The direct equity owners of the
     borrower are permitted to incur mezzanine debt subject to certain
     conditions, including: (i) the aggregate loan-to-value ratio of the Hyatt
     Regency Dallas Loan and the mezzanine loan is not in excess of 85%, and
     (ii) the debt service coverage ratio for the immediately preceding twelve
     month period ending on the last day of a fiscal quarter is not less than
     1.20x.

o    TERRORISM INSURANCE. The loan documents require the borrower to maintain
     the "all-risk" insurance in an amount equal to 100% of the full replacement
     cost of the Hyatt Regency Dallas Property, provided that the deductible
     does not exceed the sum of $25,000, unless otherwise agreed to in writing
     by lender. However, the borrower will not be required to obtain coverage
     for terrorism in excess of the outstanding balance of the Hyatt Regency
     Dallas Loan or obtain terrorism insurance if the premium for the
     comprehensive "all-risk" insurance that includes terrorism would exceed
     225% of the base rate of the comprehensive "all-risk" insurance if there
     was an exclusion for terrorism. The borrower may decide not to have
     coverage for terrorism included as part of the "all-risk" insurance policy
     and purchase terrorism insurance under a separate policy; provided that,
     the borrower will not be required to pay an insurance premium for separate
     terrorism insurance in excess of 125% of the premium payable in connection
     with the comprehensive "all-risk" insurance (exclusive of the terrorism
     insurance). The borrower may also obtain terrorism insurance under a
     "blanket" insurance policy, which covers other properties in addition to
     the Hyatt Regency Dallas Property, on terms and conditions consistent with
     the requirements for terrorism insurance as described above. See "Risk

     first four months of 2005 have exceeded the borrower's budget.

o    THE LOAN. The mortgage loan (the "ASTOR CROWNE PLAZA LOAN") is evidenced by
     two notes, one in the original principal amount of $68,850,000 and one in
     the original principal amount of $16,150,000, and is secured by multiple
     cross-defaulted and cross-collateralized mortgages, without release
     provisions, encumbering the real properties currently known as (i) the
     Astor Crowne Plaza Hotel located in New Orleans, Louisiana (the "BOURBON
     HOTEL PROPERTY"), and (ii) the Alexa Hotel located in New Orleans,
     Louisiana (the "ROYAL BOUTIQUE PROPERTY"). The hotels are collectively
     known as the "ASTOR CROWNE PLAZA PROPERTY." The Astor Crowne Plaza Loan
     represents approximately 2.1% of the initial mortgage pool balance. The
     Astor Crowne Plaza Loan was originated on March 10, 2005, had an original
     principal balance of $85,000,000 and a principal balance as of the cut-off
     date of $85,000,000, and an interest rate of 7.055% per annum. The DSCR and
     LTV on the Astor Crowne Plaza Loan are 1.40x and 77.3%, respectively. The
     proceeds of the Astor Crowne Plaza Loan were used to facilitate a
     partnership buyout of the 58% interest in the properties that were not
     controlled by the sponsors of the borrowers. The agreed upon purchase price
     was $109,275,000.

     The Astor Crowne Plaza Loan has an initial term of 120 months and a
     remaining term of 118 months. The Astor Crowne Plaza Loan requires payments
     of interest-only for 12 months and then amortizes based on a 300-month
     schedule with required monthly payments of $603,747.92 beginning May 6,
     2006. The scheduled maturity date is April 6, 2015. Voluntary prepayment of
     the Astor Crowne Plaza Loan is prohibited prior to the payment date of
     December 6, 2014 and permitted on such payment date and thereafter without
     penalty. Defeasance with United States government securities is permitted
     from July 6, 2007.

o    THE PROPERTY. The Bourbon Hotel Property is a 515-room (364,813 square
     foot) 16-story hotel that is located on Canal Street between Bourbon and
     Royal Streets in New Orleans, Louisiana. The primary Bourbon Hotel Property
     was built in 2002. The Royal Boutique Property is a 192-room (111,627
     square foot) 6-story hotel that is located on Royal Street between Canal
     and Iberville Streets in New Orleans, Louisiana. The Royal Boutique
     Property was built in the 1920's and was fully renovated in 2002. The hotel
     properties include ground floor retail spaces that are leased and operated
     by unrelated third parties.

     The Bourbon Hotel Property and the Royal Boutique Property will operate
     under one flag (Crowne Plaza) once certain project improvement plan ("PIP")
     work required by the franchisor under the franchise agreement is completed
     on the Royal Boutique Property, which is expected to be completed on or
     before July 31, 2005. The PIP includes installation of new bedding and case
     goods in late June and upgrades to lobby and signage in mid July.

     Both properties are currently the beneficiaries of real estate tax
     abatements that expire on December 31, 2007 (during the loan term). At the
     city's option, the tax abatements may be extended through December 31,
     2012. The borrowers are required to post a letter of credit in the event
     the current tax abatements are not extended through 2012 and certain cash
     flow hurdles are not achieved. The actual abatement approximates $1.3
     million based on an estimate of a non abated tax liability for calendar
     year 2005. Property cash flows were underwritten using the budgeted tax
     figure for 2005 which

     The Royal Boutique Property is subject to a triple net long term operating
     lease (the "HTC LEASE") between Royal Boutique Borrower, as landlord, and
     Royal Boutique Hotel Operating Company, as tenant (the "HTC TENANT").
     Pursuant to a Subordination and Attornment Agreement, the HTC Lease is
     subordinate to the Astor Crowne Plaza Loan, and may be terminated by lender
     in connection with a foreclosure action. Additionally, in order to secure
     the lease obligations under the HTC Lease, the HTC Tenant has pledged to
     the landlord all of its interest in and to the leases, subleases, FF&E,
     accounts and other collateral, which in turn was pledged by Royal Boutique
     Borrower to lender.

                (2)  Trailing 12 months ended April 30, 2005.

o    GROUND LEASES. The Bourbon Hotel Borrower has a leasehold interest in a
     portion of the Bourbon Hotel Property pursuant to two separate ground
     leases (the "IBERVILLE GROUND LEASE" and the "CITY OF NEW ORLEANS GROUND
     LEASE," and together, the "BOURBON HOTEL GROUND LEASES"). The Iberville
     Ground Lease has a term that expires on April 30, 2040 (with ten successive
     six year renewal terms), and the City of New Orleans Ground Lease has a
     term that expires on December 31, 2009 (with renewal terms that may be
     exercised by Bourbon Hotel Borrower through September 30, 2045). The Royal
     Boutique Borrower's ownership interest in the Royal Boutique Property is
     comprised of (i) leasehold interests under three separate ground leases
     (the "ROYAL BOUTIQUE GROUND LEASES"), each of which has a term that expires
     on January 31, 2062 (with six successive five year renewal terms) and (ii)
     ownership of a condominium unit (covering 42,335 square feet), which
     condominium is subject to a long term ground lease with McDonald's
     Corporation that expires on December 31, 2100. The Bourbon Hotel Ground
     Leases and the Royal Boutique Ground Leases contain standard mortgagee
     protection provisions, except that the Iberville Ground Lease does not does
     not contain an express provision granting the lender the right to a new
     lease upon rejection of the ground lease by the tenant in a bankruptcy
     proceeding. See "Risk Factors--Ground Leases and Other Leasehold Interests"
     in the prospectus supplement.

o    THE BORROWERS. The borrowers, Royal Boutique, L.L.C., a Louisiana limited
     liability company ("ROYAL BOUTIQUE BORROWER") and Bourbon Hotel, LLC, a
     Louisiana limited liability company ("BOURBON HOTEL BORROWER"), are each a
     special purpose, bankruptcy-remote entity with at least one independent
     director. Legal counsel to the borrowers delivered a non-consolidation
     opinion in connection with the origination of the Astor Crowne Plaza Loan.
     The sole managing member of the Royal Boutique Borrower is Royal Delaware,
     LLC, a special purpose, bankruptcy-remote, Delaware limited liability
     company with an independent director. The sole managing member of the
     Bourbon Hotel Borrower is Bourbon Delaware, LLC, a special purpose,
     bankruptcy-remote, Delaware limited liability company with an independent
     director. Royal Boutique Borrower is the owner of the Royal Boutique
     Property and Bourbon Hotel Borrower is the owner of the Bourbon Hotel
     Property. The mortgage encumbering the Royal Boutique Property and the
     mortgage encumbering the Bourbon Hotel Property have been
     cross-collateralized and cross-defaulted with each other. F. Patrick Quinn
     and Edwin Palmer, III guaranteed the non-recourse carveouts of the Astor
     Crowne Plaza Loan.

TEN LARGEST MORTGAGE LOANS - ASTOR CROWNE PLAZA
--------------------------------------------------------------------------------

o    ESCROWS. The loan documents provide for certain escrows for real estate
     taxes and insurance. At closing, the borrowers deposited $332,750 into a
     PIP work reserve for the payment of certain PIP work required by the
     franchisor under the franchise agreement. The loan documents also require
     (i) the Bourbon Hotel Borrower to make monthly payments in an amount of 4%
     of the annual gross revenues related to hotel operations at the Bourbon
     Hotel Property and (ii) the Royal Boutique Borrower to cause HTC Tenant to
     pay not less than 4% of the annual gross revenues related to hotel
     operations at the Royal Boutique Property for approved capital expenses.
     The loan documents also require the borrowers to make monthly payments for
     any installment of ground rent under each ground lease.

o    LOCKBOX AND CASH MANAGEMENT. The loan requires a hard lockbox, which is
     already in place. The loan documents require that all rents received by the
     borrowers and HTC Tenant be deposited within three business days into a
     clearing account, which amounts are then swept into a borrower-controlled
     account, unless a Cash Management Period is in effect. A "CASH MANAGEMENT
     PERIOD" is a period during which (i) an event of default (as defined in the
     loan documents) is continuing, until such event of default is cured, or
     (ii) the DSCR is less than 0.99x (based on the net operating income of the
     Astor Crowne Plaza Property and a stressed debt service constant of 8.65%)
     as of the end of any calendar quarter (a "DSCR CASH MANAGEMENT PERIOD"),
     until the DSCR minimum threshold has been achieved for two consecutive
     calculation dates after the commencement of the Cash Management Period; or
     (iii) an approved mezzanine loan is outstanding. During the continuance of
     a Cash Management Period, all available cash after payment of debt service,
     operating expenses and required reserves is required to be deposited into a
     lender-controlled account and held as additional cash collateral for the
     Astor Crowne Plaza Loan and may be applied to prepay the Astor Crowne Plaza
     Loan during the continuance of an event of default. Additionally, if a DSCR
     Cash Management Period is continuing for three consecutive calendar
     quarters, lender may use the additional cash collateral to purchase
     defeasance eligible collateral and apply the proceeds of such collateral to
     pay a portion of the monthly payments due under the Astor Crowne Plaza Loan
     each month.

o    PROPERTY MANAGEMENT. Decatur Hotels, LLC, an affiliate of the borrowers, is
     the property manager for the Astor Crowne Plaza Property. The lender may
     replace the property manager if (i) an event of default is continuing under
     the Astor Crowne Plaza Loan, (ii) the property manager defaults under the
     property management agreement, or (iii) upon the gross negligence,
     malfeasance or willful misconduct of the property manager. The property
     manager is entitled to receive a base management fee equal to 3.0% of gross
     revenues.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. There is currently no mezzanine or
     subordinate indebtedness. The loan documents permit mezzanine financing
     from and after April 6, 2010 from an approved mezzanine lender to the
     holder or holders of all of the direct and indirect ownership interests in
     borrowers, provided that the approved mezzanine lender enters into an
     intercreditor agreement with lender, the borrowers deliver a Rating Agency
     "comfort letter", and that the mezzanine loan: (i) will be in an amount
     that when added to the Astor Crowne Plaza Loan will result in a combined
     loan to "as is" appraised value of the Astor Crowne Plaza Property of up to
     78%, (ii) will result in a minimum combined debt service coverage ratio of
     not less than 1.20x, (iii) is secured only by a pledge of all or a portion
     of the direct or indirect equity ownership interests in borrowers or any
     other collateral that is not collateral for the Astor Crowne Plaza Loan,
     (iv) creates no obligations or liabilities on the part of the borrowers and
     does not result in any lien on any portion of any Mortgaged Property, (v)
     has a term expiring on the stated maturity date for the Astor Crowne Plaza
     Loan and, (vi) is otherwise on terms and conditions reasonably acceptable
     to lender and evidenced by loan documents which have been reasonably
     approved by lender.

o    TERRORISM INSURANCE. The Astor Crowne Plaza Property is insured against
     acts of terrorism as part of its "all-risk" property coverage. The loan
     documents require the borrowers to maintain terrorism insurance in an
     amount equal to 100% of the full replacement cost of the Astor Crowne Plaza
     Property, provided that such coverage is available as part of the
     "all-risk" property coverage. In the event terrorism insurance is not
     included as part of the "all-risk" property policy, the borrower will be
     required to purchase terrorism insurance at a cost up to the Terrorism
     Premium Cap (defined below). If the insurance premiums for such policy
     exceed the Terrorism Premium Cap, the lender may, at its option (1)
     purchase such stand-alone terrorism insurance policy, and require that the
     borrowers pay the portion of the premiums equal to the

     Terrorism Premium Cap or (2) modify the deductible amounts, policy limits
     and other required policy terms to reduce the insurance premiums payable
     with respect to such stand-alone terrorism policy to the Terrorism Premium
     Cap. As used herein, "TERRORISM PREMIUM CAP" means an amount which is equal

o    THE LOAN. The mortgage loan (the "ONE HSBC CENTER TRUST LOAN") is evidenced
     by a single note and is secured by a first mortgage encumbering a 851,915
     square foot class-A office building and an adjacent 820-space parking
     garage in Buffalo, New York (the "ONE HSBC CENTER PROPERTY"). The One HSBC
     Center Trust Loan represents approximately 1.9% of the initial mortgage
     pool balance. The One HSBC Center Trust Loan was originated on January 14,
     2005, has an original principal balance and a balance as of the cut-off
     date of $78,000,000, and an interest rate of 6.20% per annum. The DSCR and
     LTV on the One HSBC Center Trust Loan are 1.31x and 76.5%, respectively.
     The proceeds of the One HSBC Center Trust Loan facilitated the acquisition
     of the One HSBC Center Property by the borrower for a purchase price of
     $93,600,000. Including costs, reserves and escrows of approximately
     $5,160,000, the borrower invested approximately $15,760,000 in the project
     at origination.

     The One HSBC Center Trust Loan is the senior portion of a whole mortgage
     loan with an original principal balance of $83,000,000. The companion loan
     to the One HSBC Center Trust Loan is evidenced by a separate note with an
     original principal balance of $5,000,000 and a principal balance as of the
     cut-off date of $5,000,000 and an interest rate of 6.20% per annum (the
     "ONE HSBC CENTER SUBORDINATE COMPANION LOAN"). The One HSBC Center
     Subordinate Companion Loan is not an asset of the trust. The One HSBC
     Center Trust Loan and the One HSBC Center Subordinate Companion Loan
     (collectively, the "ONE HSBC CENTER LOAN GROUP") are governed by a
     co-lender agreement, as described in the prospectus supplement under
     "Description of the Mortgage Pool--The Whole Loans" and will be serviced
     pursuant to the terms of the 2005-GG4 pooling and servicing agreement. The
     DSCR and LTV on the One HSBC Center Loan Group are 1.23x and 81.4%,
     respectively.

     The One HSBC Center Trust Loan has an initial term of 120 months and a
     remaining term of 116 months. The loan requires payments of interest only
     for 60 months and then amortizes thereafter based on a 360-month
     amortization schedule, with required monthly payments of $477,725.80
     beginning March 6, 2010. The scheduled maturity date is February 6, 2015.
     Voluntary prepayment of the One HSBC Center Trust Loan is prohibited until
     November 6, 2014 and permitted thereafter without penalty. Defeasance with
     United States government securities or other approved non-callable
     government securities is permitted from July 6, 2007.

o    THE PROPERTY. The One HSBC Center Property is a 40-story, multi-tenant
     office tower comprising 851,915 square feet, plus an 820-space adjacent
     parking garage, located in the Buffalo central business district. The
     building is constructed above Main Street, which is a pedestrian and
     MetroRail thoroughfare. Completed in 1972, the building contains 851,915
     square foot of class-A office space and a variety of amenities including a
     full-service bank, cafeteria, newsstand and deli. Investment-grade tenants
     and subsidiaries of investment-grade companies occupy 82.4% of the One HSBC
     Center Property and include HSBC Bank USA, NA, Canadian Consulate, UBS
     Financial Services, and Advest (subsidiary of AXA).

     The largest tenant is HSBC Bank USA, NA ("HSBC BANK"), which occupies
     653,848 square feet (76.8% of NRA). The headquarters of HSBC Bank USA is
     located at the One HSBC Center Property. The HSBC lease expires in October,

     The parking garage at the One HSBC Center Property is subject to a lease
     (the "ONE HSBC CENTER GARAGE LEASE") from the Erie County Industrial
     Development Agency. The One HSBC Center Garage Lease provides the borrower
     the benefit of reduced real estate taxes under a local government program
     of payment in lieu of taxes (i.e., a PILOT program). The One HSBC Center
     Garage Lease expires on September 2, 2007, at which time the fee interest
     in the garage portion of the One HSBC Center Property will automatically be
     conveyed to the borrower for consideration no greater than $10.00. In

     addition, at any time prior to September 2, 2007, the borrower has the
     option to purchase the fee interest in the garage portion of the One HSBC
     Center Property for $10.00. Upon an event of default by the borrower under
     the One HSBC Center Garage Lease, the lessor's sole remedy is to terminate
     the One HSBC Center Garage Lease and simultaneously convey the fee interest
     in the garage portion to the borrower for $10.00.

o    THE BORROWER. The borrower, Seneca One Realty LLC, is a single-asset,
     bankruptcy remote entity with an independent director. Legal counsel to the
     borrower delivered a non-consolidation opinion in connection with the
     origination of the One HSBC Center Trust Loan. The sponsor of the borrower
     is Mark Karasick. Two individuals, Avy Azeroual and Charles Ishay, each own
     25% of the borrowing entity. Mr. Karasick guaranteed the non-recourse
     carveouts of the One HSBC Center Trust Loan. As of November 30, 2004, Mr.
     Karasick reported a net worth of $90,460,000 and liquidity of $9,895,000.
     Mr. Karasick has been actively involved in real estate investment,
     ownership and management for nearly 25 years.

o    ESCROWS. The loan documents provide for certain escrows of real estate
     taxes (including any PILOT payments payable under the One HSBC Center
     Garage Lease) and insurance premiums. Additionally, the loan documents
     require the borrower to make monthly payments totaling $170,379 per year
     for replacement reserves, $127,787 per year for a tenant improvement and
     leasing commission reserve and monthly payments totaling $50,000 per year
     for potential tenant improvement obligations owed to Phillips Lytle. The
     borrower is also required to deposit any lease termination payments and
     security deposits applied or other payments received on account of lease
     defaults or lease terminations into the tenant improvement and leasing
     commission reserve. At closing, the borrower deposited $600,879 into the
     tenant improvement and leasing commission reserve account, of which
     $100,879 was deposited to cover current and future landlord obligations to
     existing tenants and $500,000 was deposited for future leasing expenses.

     The loan documents also provide for an additional springing tenant
     improvement and leasing commission reserve (the "ONE HSBC CENTER MAJOR
     LEASE RESERVE") which will commence in the event that either of the leases
     (or any material portion of the leases) to HSBC Bank or Phillips Lytle at
     the One HSBC Center Property is surrendered, cancelled or terminated prior
     to its then current expiration date or in the event that either
     discontinues its business at the One HSBC Center Property or fails to give
     notice of renewal of its lease at the One HSBC Center Property.

o    LOCKBOX AND CASH MANAGEMENT. The loan requires a hard lockbox, which is
     already in place. The loan documents require that all rents received by (or
     on behalf of) the borrower be deposited into a lender-controlled account
     (as well as any other rents, receipts, security deposits or payments
     related to lease termination or default) within three business days after
     receipt. Unless a One HSBC Center Cash Trap Period is in effect, any excess
     amounts in the lender-controlled account (after the payment of debt service
     and all monthly reserve payments) is disbursed to the borrower. A "ONE HSBC
     CENTER CASH TRAP PERIOD" means any period during which (i) an event of
     default (as defined in the loan documents) has occurred and is continuing,
     until the event of default is cured, (ii) the DSCR (based on actual net
     cash flow and a 7% constant) as of the end of any calendar quarter is less
     than 1.08x, until this DSCR minimum threshold has been achieved for two
     consecutive calendar quarters, and (iii) during any time that the One HSBC
     Center Major Lease Reserve is triggered, as described under "Escrows"
     above.

o    PROPERTY MANAGEMENT. The One HSBC Center Property is self-managed by the
     borrower. In connection with the acquisition of the One HSBC Center
     Property and the origination of the One HSBC Center Trust Loan, the
     borrower hired the significant employees of the management company employed
     by (and affiliated with) the seller of the One HSBC Center Property. Such
     management company had been the manager of the One HSBC Center Property for
     six years prior to the acquisition of the One HSBC Center Property by the
     borrower. In the event a management company is engaged by the borrower,
     such management company must first be approved by the lender. In addition
     the lender may require the appointment of a manager, or the replacement of
     any existing manager, if (i) for any two consecutive calendar quarters, the
     borrower fails to maintain a DSCR (based on actual net cash flow and a 7%
     constant) of at least 1.08x, (ii) an event of default is continuing, (iii)
     a manager is in default under its management agreement, (iv) upon the gross
     negligence,

     malfeasance or willful misconduct of a manager or (v) either one of Judy K.
     Tallman or Stephen P. Fitzmaurice are no longer employed by the borrower in
     a position or positions pursuant to which they collectively are primarily
     responsible for the management and operation of the One HSBC Center
     Property (and the borrower has not replaced one or both of them (as
     applicable) with one or more employees reasonably acceptable to lender
     within thirty (30) days of the termination of their employment or their
     resignation, as may be applicable).

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. Not permitted.

o    TERRORISM INSURANCE. The One HSBC Center Property is insured against acts
     of terrorism as part of its "all-risk" property coverage. The loan
     documents require the borrower to maintain terrorism insurance in an amount
     equal to 100% of the replacement cost of the One HSBC Center Property,
     provided that such coverage is available. See "Risk Factors--Property
     Insurance" in the prospectus supplement.

TEN LARGEST MORTGAGE LOANS - FESTIVAL AT BEL AIR
--------------------------------------------------------------------------------

     consists of 29 community shopping centers and nine freestanding retail
     sites in Maryland, Virginia and Washington D.C. with a total of
     approximately 5.5 million sf.

o    ESCROWS. At origination, the borrower deposited $419,463 into a reserve
     account for real estate taxes and $668,750 into a reserve account for
     deferred maintenance. The loan documents require the borrower to make
     monthly payments of $46,607 for real estate taxes. The requirement to
     reserve for insurance is suspended as long as the borrower submits proof of
     payment that the insurance has been prepaid for a 12-month period.
     Additionally, the borrower is required to deposit into an escrow fund all
     funds received from the tenants in connection with the cancellation of any
     leases. These funds will be released to the borrower upon the execution of
     a lease covering the space that had been covered by the cancelled lease and
     the satisfaction of certain other conditions so long as no event of default
     exists under the loan documents at that time.

o    PROPERTY MANAGEMENT. The Festival at Bel Air Property is managed by
     JBG/Rosenfeld Retail Properties LLC, an affiliate of the borrower. The
     lender may terminate the property manager upon the occurrence and during
     the continuance of an event of default under the loan documents. The
     management agreement for the Festival at Bel Air Property provides for
     management fees as follows: (i) a monthly management fee equal to 3.5% of
     all gross income from the Festival at Bel Air Property; (ii) a leasing
     commission on each lease for space in the Festival at Bel Air Property in
     the amount of 4% of the aggregate minimum rent payable under such lease
     over its term; and (iii) a fee for its construction, administration and
     coordination services ranging from 10% to 5% of the costs of the
     construction project ranging from $250,000 to $1,000,000 and higher,
     respectively. The borrower may not terminate, cancel, modify, renew or
     extend the existing management agreement or enter into any other agreement
     relating to the management of the Festival at Bel Air Property without the
     express consent of the lender.

o    MEZZANINE OR SUBORDINATE INDEBTEDNESS. Not permitted.

o    TERRORISM INSURANCE. The loan documents require the borrower to maintain
     the "all-risk" insurance in an amount equal to 100% of the full replacement
     cost of the Festival at Bel Air Property with a deductible that does not
     exceed $10,000. See "Risk Factors--Property Insurance" in the prospectus
     supplement.
