 Notes:
 1. NR = not rated.
 2. Classes D, X-D, E, F-RR, G-RR, and HRR will be privately placed.
 3. The Class X-A, X-B, and X-D balances are notional. Classes X-A, X-B, and X-D are IO certificates that reference a single rated tranche or multiple rated tranches. The IO
     rating mirrors the lowest-rated reference tranche adjusted upward by one notch if senior in the waterfall.
 4. The exact initial certificate balances of the Class A-4 and Class A-5 certificates are unknown and will be determined based on the final pricing of those classes of certificates.
     However, the respective initial certificate balances, assumed final distribution date, weighted average lives and principal windows of the Class A-4 and Class A-5 certifi-
     cates are expected to be within the applicable ranges reflected in the following chart. The initial aggregate certificate balance of the Class A-4 and Class A-5 certificates is
     expected to be approximately $746,198,000, subject to a variance of plus or minus 5%.
 5. Loan specific certificates: Classes SW-A, SW-B, SW-C, SW-D, and SW-VR are loan-specific certificates collateralized by the subordinate companion loan component of
     the Starwood Class A Industrial Portfolio 1 whole loan. The loan-specific certificates will only be entitled to receive distributions from, and will only incur losses with respect
     to, the trust subordinate companion loan. The trust subordinate companion loan is included as an asset of the issuing entity but is not part of the mortgage pool backing the
     pooled certificates. No class of pooled certificates will have any interest in the trust subordinate companion loan.

Rating Considerations
The collateral consists of 52 fixed-rate loans secured by 152 commercial, hospitality, and multifamily properties. The
transaction is a sequential-pay pass-through structure. DBRS Morningstar analyzed the conduit pool to determine the
provisional ratings, reflecting the long-term probability of loan default within the term and its liquidity at maturity. DBRS
Morningstar shadow-rated eight loans, representing 31.8% of the pool, as investment grade. When the cutoff loan balances
were measured against the DBRS Morningstar Stabilized NCF and their respective actual constants, nine loans, representing
9.9% of the pool, had a DBRS Morningstar Term DSCR below 1.32x, a threshold indicative of a higher likelihood of midterm
default. The pool additionally includes 14 loans, representing 23.4% of the pool by allocated loan balance, with issuance
LTVs higher than 67.1%, a threshold historically indicative of above-average default frequency. The WA LTV of the pool at
issuance was 54.6% and the pool is scheduled to amortize down to a WA LTV of 51.4% at maturity.

STRENGTHS
– Investment-grade component: The collateral features eight loans, representing 31.8% of the initial pool balance,
  that DBRS Morningstar assessed as investment grade: 1633 Broadway, 560 Mission Street, Starwood Class A Industrial
  Portfolio 1, Bellagio Hotel and Casino, Southcenter Mall, 650 Madison Avenue, Parkmerced, and 510 East 14th Street. DBRS
  Morningstar views the percentage of investment-grade loans in the pool favorably and the proportion of investment-grade
  loans is higher than other recent conduit/fusion transactions. For more information on these eight loans, please refer to
  their respective loan summaries.
– Portfolio diversification and granularity: The pool is relatively granular and does not exhibit significant loan size
  concentration. No loan represents more than 4.5% of the pool cutoff balance and the top 10 loans represent only 42.1%
  of the total pool balance. Eight loans, representing 17.7% of the initial pool balance, are secured by multiple-property
  portfolios, which provides additional diversity and cash flow stability compared with a loan collateralized by a single
  property. Additionally, no single property type accounts for more than 25.0% of the pool by initial cutoff balance.
– Quality and pool metrics: The pool has a favorable WA DBRS Morningstar LTV of 54.5% at issuance, which amortizes
  down to a WA DBRS Morningstar Ending LTV of 51.4% at maturity, which is lower than recent transactions. Eight loans,
  representing 42.0% of the sampled loans, had Average (+), Above Average, or Excellent property quality. Additionally, only
  one loan, representing 1.4% of the sampled loans, had Below Average property quality. Four of the five largest loans in the
  pool, representing 27.0% of the initial pool balance, are rated either Excellent or Above Average.
– Loan Purpose and cash equity: Approximately 37.8% of the pool by initial cutoff balance is for the purpose of acquisition,
  which DBRS Morningstar views as favorable in the context of recent-vintage conduit/fusion transactions. Cash equity
  infusions from a sponsor in a transaction typically results in a greater alignment of interests between the lender and
  borrower, especially compared with a refinancing scenario where the sponsor may be withdrawing equity from the
  transaction. Several loans that produced higher-than-average expected losses, including PCI Pharma Portfolio, Magnolia
  Parc, and Harvey Building Products, were used to fund acquisitions with a WA cash equity of 31.5% of the purchase price.

– Leverage barbelling: The pool exhibits heavy-leverage barbelling. While the pool has 21 loans, comprising 54.3% of
  the pool balance, with an issuance LTV lower than 59.3%, a threshold historically indicative of relatively low-leverage
  financing and generally associated with below-average default frequency, there are also 18 loans, comprising 21.2% of
  the pool balance, with an issuance LTV higher than 67.1%, a threshold historically indicative of relatively high-leverage
  financing and generally associated with above-average default frequency. The WA Expected Loss of the pool’s investment-
  grade component was approximately 0.6% while the WA Expected Loss of the pool’s conduit component was substantially
  higher at over 3.0%, further illustrating the barbelled nature of the transaction.
    – Seventeen of the 18 loans identified as high leverage have some form of amortization and the 18 loans collectively amortize
      down to a WA LTV of 62.0% at maturity and have an average occupancy rate of 96.8%. Additionally, 11 of the 18 high-
      leverage loans are for the purpose of acquisition.

– IO concentration: Twenty-nine loans, representing a combined 68.2% of the cutoff pool balance, are structured with full-
  term IO periods and an additional 17 loans, representing 26.5% of the pooled cutoff balance, are structured with partial-IO
  terms ranging from 12 months to 60 months.
    – Eight of the loans structured with full-term IO periods are shadow-rated investment grade and represent nearly half of
      the 67.5% IO concentration.
– Secondary/tertiary market concentration: The pool features a relatively high concentration of loans secured by
  properties located in less favorable suburban market areas. Twenty-six loans, representing 49.9% of the pool’s cutoff
  balance, are secured by properties predominately located in areas with a DBRS Morningstar Market Rank of either 3 or 4.
    – Loans in markets with a DBRS Morningstar Market Rank of either 3 or 4, on average, produce higher expected losses
      than similar loans; therefore, the component of the pool that is concentrated in these weaker markets resulted in higher
      deal-level credit enhancement with the WA expected loss of over 3.0% for the conduit component of the transaction.
    – The pool also has six loans, representing 17.5% of the cutoff pool balance, that are in areas with a DBRS Morningstar
      Market Rank of 7 or 8.
– Legal and structural considerations: Four loans, representing 12.0% of the pool by initial balance, are secured by either
  a leasehold or partial leasehold interest. Crystal Springs Resort, representing 3.8% of pool, is secured by a condominium
  interest that DBRS Morningstar deems to be credit negative.
    – The ground leases generally have fully extended expiration dates far enough in the future to be considered traditionally
      financeable or otherwise do not encumber a portion of the property that generates a material amount of value. With respect
      to Crystal Springs Resort, the very high 9.1% implied cap rate reflects the great risk inherent in the collateral package.

DBRS Morningstar completed a cash flow review as well as
a structural review on 23 of the 52 loans, representing 66.8% of the pool by allocated loan balance. DBRS Morningstar
generally adjusted cash flows to current in-place rent and, in some instances, applied an additional vacancy or concession
adjustment to account for deteriorating market conditions or tenants with above-market rents. In certain instances, DBRS
Morningstar accepted contractual rent steps if they were within market levels. Most expenses were generally recognized
based on the higher of historical figures or the borrower’s budgeted figures. Real estate taxes and insurance premiums
were inflated if a current tax bill was not provided. Capex was deducted based on the higher of the engineer’s inflated
estimate and the DBRS Morningstar standard, according to property type. Finally, leasing costs were deducted to arrive at
the DBRS Morningstar NCF. If a significant upfront leasing reserve was established at closing, DBRS Morningstar reduced
its recognized costs. DBRS Morningstar gave credit to tenants not yet in occupancy if a lease was signed and the loan was
adequately structured with a reserve, LOC, or holdback earn-out. The DBRS Morningstar sample had an average NCF
variance of -12.6% and ranged from -1.5% (Parkmerced) to -37.6% (90 North Campus). For loans not subject to an NCF
review, DBRS Morningstar applied the average NCF variance of the sampled loans.

Model Adjustments

DBRS Morningstar applied POD and LGD assumptions to certain loans, including Starwood Class A Industrial Portfolio 1,
Crystal Springs Resort, Southcenter Mall, Van Aken District, PCI Pharma Portfolio, Harvey Building Products, Broadcasting
Square, and 349 Coleman Boulevard. Identified model adjustments were as follows:
– DBRS Morningstar adjusted the POD assumption for Starwood Class A Industrial Portfolio 1 downward to reflect the
  investment-grade nature of the A note contributed to the transaction (the subordinate companion note was analyzed
  separately).
– DBRS Morningstar adjusted the POD assumption for Crystal Springs Resort downward based on the analyst’s extensive
  site inspection of the property, which was net positive on DBRS Morningstar’s view of the asset.
– DBRS Morningstar adjusted the POD and LGD assumptions for Southcenter Mall to reflect an upward cap-rate adjustment
  to the DBRS Morningstar adjusted cap rate of 5.5% from the Issuer’s implied cap rate of 4.2%. This resulted in adjusted
  DBRS Morningstar Issuance and Maturity LTVs of 28.8%, which DBRS Morningstar then applied to its POD and LGD
  calculations. DBRS Morningstar made the cap-rate adjustment for this loan to bring the cap rate to a level that is more
  consistent with other regional malls.
– DBRS Morningstar adjusted the POD and LGD assumptions for Van Aken District to reflect an upward cap-rate adjustment
  to the DBRS Morningstar adjusted cap rate of 5.0% from the Issuer’s implied cap rate of 4.7%. This resulted in adjusted
  DBRS Morningstar Issuance and Maturity LTVs of 58.1%, which DBRS Morningstar then applied to its POD and LGD
  calculations. DBRS Morningstar made the cap-rate adjustment for this loan to bring the cap rate to a level that is consistent
  with similar mixed-use assets in secondary markets.
– DBRS Morningstar adjusted the POD and LGD assumptions for PCI Pharma Portfolio to reflect an upward cap-rate
  adjustment to the DBRS Morningstar adjusted cap rate of 6.1% from the Issuer’s implied cap rate of 5.8%. This resulted
  in adjusted DBRS Morningstar Issuance and Maturity LTVs of 62.3%, which DBRS Morningstar then applied to its POD
  and LGD calculations. DBRS Morningstar made the cap-rate adjustment for this loan to account for the specialty use,
  including packaging, research and development, and cold storage.
– DBRS Morningstar adjusted the POD and LGD assumptions for Harvey Building Products to reflect an upward cap-rate
  adjustment to the DBRS Morningstar adjusted cap rate of 7.0% from the Issuer’s implied cap rate of 5.9%. This resulted in
  adjusted DBRS Morningstar Issuance and Maturity LTVs of 82.7% and 74.9%, respectively, which DBRS Morningstar then
  applied to its POD and LGD calculations. DBRS Morningstar made the cap-rate adjustment to account for the specialty-
  use (manufacturing) nature of some of the collateral.
– DBRS Morningstar adjusted the POD and LGD assumptions for Broadcasting Square to reflect an upward cap-rate
  adjustment to the DBRS Morningstar adjusted cap rate of 6.5% from the Issuer’s implied cap rate of 5.8%. This resulted
  in adjusted DBRS Morningstar Issuance and Maturity LTVs of 58.1%, which DBRS Morningstar then applied to its POD and
  LGD calculations. DBRS Morningstar made the cap-rate adjustment to account for the secondary location of the retail asset.
– DBRS Morningstar adjusted the POD and LGD assumptions for 349 Coleman Boulevard to reflect an upward cap-rate
  adjustment to the DBRS Morningstar adjusted cap rate of 6.5% from the Issuer’s implied cap rate of 5.4%. This resulted
  in adjusted DBRS Morningstar Issuance and Maturity LTVs of 76.4%, which DBRS Morningstar then applied to its POD
  and LGD calculations. DBRS Morningstar made the cap-rate adjustment to account for the secondary location.

Leasehold: 510 East 14th Street, representing 2.6% of the pool by allocated loan balance, is fully secured by the borrower’s
leasehold interest in the property. The ground lease has a scheduled expiry of November 27, 2111, and the ground-rent
payment of $2.6 million at issuance represents 23.1% of the DBRS Morningstar NCF of over $8.6 million. During the loan
term, the ground rent will be no more than 25.5% of the DBRS Morningstar NCF. The ground lease has an expiration
date far enough beyond loan amortization to be considered traditionally financeable; however, the appraiser concluded
a 2041 ground-rent reset of $11.2 million, which will fall at the end of the subsequent loan term and may affect this loan’s
refinancability.

The building also is home to the Circle in the Square Theatre and the Circle in the Square Theatre School, with entry on
50th Street. In addition, part of the collateral is a building adjacent to the main office tower containing a 250-space valet
parking garage with a ground-floor entrance and the 1,933-seat Gershwin Theatre above the garage. The Gershwin Theatre
is the largest Broadway theater based on seating capacity and has hosted Wicked since 2003.

The property competes with numerous other Class A office buildings of similar vintage in the Westside office submarket
as defined by the appraiser. Reis identifies 10 properties built in the 1970s in the Midtown West submarket that make up its
competitive set and another 11 office buildings of newer vintage that are direct competitors. The office vacancy rate for the
Westside submarket for Q3 2019 was 5.4%, per the appraiser. For the same time period, Reis estimated vacancy was 7.8% for
the Midtown West submarket, with 7.2% vacancy for Class A office properties. However, approximately 21.9 million sf of
development is scheduled for completion in Manhattan by 2023, and another 12.6 million sf is in the planning stages. DBRS
Morningstar believes the new supply in midtown Manhattan, the bulk of which is the midtown Manhattan, particularly in
Hudson Yards, could significantly affect the marketability and occupancy of existing buildings in the submarket. Similarly,
Reis projects the submarket’s vacancy to increase to 9.4% in 2023.

SPONSORSHIP
The loan benefits from experienced and high-quality sponsor Paramount Group, a fully integrated REIT, which has its
headquarters in the building in four offices on the 18th totaling approximately 37,000 sf. Established in 1978, Paramount
Group, from which the building’s name of Paramount Plaza comes from, has a 10.4 million sf portfolio of Class A office
buildings, retail, and debt and equity investments in New York, San Francisco, and Washington, D.C. Paramount Group is
listed on the New York Stock Exchange and has a market capitalization of $3.14 billion as of December 31, 2019.

The property manager is an affiliate of Paramount Group. It manages Paramount Group’s entire real estate portfolio.

DBRS MORNINGSTAR ANALYSIS
SITE INSPECTION SUMMARY

DBRS Morningstar toured the interior and exterior of the property on October 22, 2019, at 10:00 a.m. Based on the site
inspection, DBRS Morningstar found the property quality to be Average (+).

The collateral comprises a 48-story, 2,500,000-plus sf Class A office tower with a 250-space parking garage. The property,
which has received the LEED Gold status, has large floorplates ranging from 37,000 sf to 54,000 sf.

At 1633 Broadway, the property is well located between 50th Street and 51st Street in the northern section of Manhattan’s
theater district, which is centrally located within the midtown office market. The property has excellent access to public
transportation, as eight subway lines run directly under the property and there are several public bus services in the area.
The property is near numerous iconic restaurants and retail sites augmenting the many tourist attractions in Times Square,
which is immediately south.

The site tour leaders were members of the property management company and executives of the sponsor. The property
manager is an affiliate of the sponsor. DBRS Morningstar toured several tenants’ spaces in the building, which showed
the diversity of its tenancy. Several tenants are established companies such as Morgan Stanley, Warner Brothers Music,
MongoDB, and New Mountain Capital.

The primary entrance is from Broadway, where the building is set back about 100 feet from the street. The lobby was
very active on the day of the site inspection. The front lobby entrance is impressive, with porcelain/marble floors and
ceilings approximately 30 feet high. The lobby has revolving and swinging doors that lead to a central 24-hour security
desk. Employees use the 38 passenger elevators serving the office tower. Warner Music Group has a dedicated entrance on
50th Street to its offices on six floors totaling nearly 300,000 sf.

Management began the tour on the top two floors, which were being built out for the newly signed lease to a private
equity firm. The proposed fit and finishes were on par for Class A properties. The floor design of the space included a
spiral staircase connecting the two floors and outdoor space on both floors. In addition, DBRS Morningstar observed the
building’s unobstructed views of midtown Manhattan from the top floors. Furthermore, management showed the building’s
large and open floorplates of approximately 50,000 sf per floor on all but the lower five floors.

January 2020                                                                                                            22

The DBRS Morningstar NCF is based on the DBRS Morningstar North American Commercial Real Estate Property Analysis
Criteria. The resulting DBRS Morningstar Stabilized NCF was $92,393,880, – down 20.0% from the Issuer’s NCF. The main
drivers of the variance are tenant leasing costs, rent steps, management fees, and assumed vacancy.

According to CBRE, the office property is in the Times Square/Westside submarket, which shows a tight vacancy rate of
5.5% for Class A space. Reis shows the Midtown West submarket vacancy at 7.8% for Q3 2019 for all office space in the
submarket and 5.5% vacancy for office properties of similar vintage and quality. The property has averaged 5.4% vacancy for
the past seven years. Only two years in the past 17 years have had average occupancy dip below 90%. DBRS Morningstar used
6.2% of the gross revenue as its vacancy estimate. This is lower than DBRS Morningstar’s standard 10% for office properties
because of the property’s excellent location, historically strong submarket, consistently strong property occupancy, and
current physical vacancy of 1.9%. The Issuer assumed a 4.2% vacancy on gross revenue.

DBRS Morningstar did not accept rent steps beyond the first 12 months because none of the investment-grade tenants’
leases extended more than three years beyond the loan term. In addition, DBRS Morningstar’s calculation of TI/LCs
exceeded that of the Issuer. DBRS Morningstar concluded to an average of $75 psf for new leases and $38 psf for renewal
leases and a 65% renewal percentage on a normalized basis.

DBRS Morningstar concluded to operating expenses that closely tracked the in-place amount and the T-12 ended September
2019 amount except for management fees. DBRS Morningstar assumed the management fee was 1.5% of the EGI as opposed
to the Issuer capping fees at $1.0 million, or 0.5% of the EGI.

DBRS MORNINGSTAR VIEWPOINT
DBRS Morningstar believes that the office building will perform well given its desirable location in midtown Manhattan
a few blocks north of Times Square and midway between Grand Central Terminal and Columbus Circle. Regardless of its
age of nearly 50 years, the property has kept high institutional standards comparable to other Class A space within the
submarket thanks to its most recent renovation in 1989 and more recent tenant fit-outs. The quality tenant list includes
seven credit rated tenants, representing 56.8% of the NRA and 60.9% of the total projected rent. Four tenants, representing
37% of the total space, have investment-grade ratings. Most leases are long term, resulting in consistently high occupancy
and low turnover during the loan term.

January 2020                                                                                                            23
Presale Report   |   GSMS 2020-GC45

 1633 BROADWAY – NEW YORK, NY

The area is densely developed with office buildings of similar and lesser quality. Local commercial offerings on the nearby
avenues and cross streets provide desirable entertainment and shopping venues and numerous eating establishments
including several highly rated restaurants. The property is easily assessible by subway and surface transportation. For all
these reasons plus the strong sponsorship, DBRS Morningstar believes the loan will perform up to its expectation and pay
as agreed during the loan term and is capable of a refinance takeout at the end of the loan term.

Because of the low DBRS Morningstar LTV of 68.2% based on a 6.50% capitalization rate and 41.7% appraisal LTV, the
property’s excellent location in a gateway market, and the long-term owner, DBRS Morningstar considers the credit
qualities associated with the senior notes to be A (low).

DOWNSIDE RISKS
– The office property, built in 1971 and renovated in 1989 (30 years ago), is competing with recently constructed and under
  construction office properties with substantial modern amenities and features.
– The loan has a 10-year, full-term, IO debt payment structure, which increases the risk of maturity loan default because
  there is no amortization.
– The lease expiration schedule indicates that 64.4% of the leased NRA expires before and just after loan maturity with Allianz,
  representing 15.5% of NRA, expiring in 2031. The loan does not provide for any tenant specific springing re-leasing reserve.

STABILIZING FACTORS
– DBRS Morningstar noted no deferred maintenance at the time of the site visit, and the property condition report confirmed
  minimal immediate repairs with future needs amounting to $0.20 psf per year on an inflated basis. In addition, new properties
  are commanding substantial rent premiums over the 1633 Broadway, which means they are not directly competitive.
– The tower’s floors, capable of an open, unobstructed floorplan, belie the dark and tired main lobby, which could be a
  deterrent to future competitive leasing.
– The senior notes have a low LTV of 41.7% based on the as-is appraised value, and the trust exposure at $391 psf is
  extremely attractive.
– DBRS Morningstar considers the tenant rent roll to be relatively granular as Allianz is the largest tenant at just 15.5% of
  NRA. There is an ongoing TI/LC reserve capped at $5.1 million. DBRS Morningstar views the property’s overall rent as
  below current market rates for similar properties.

 560 MISSION – SAN FRANCISCO, CA

The property is well-located a block south of Market Street on Mission Street between 1st Street and 2nd Street in San
Francisco’s financial district. The Montgomery Bay Area Rapid Transit station is about a three-minute walk north of the
property and provides convenient mass transit access. The surrounding area mainly consists of high-rise office buildings
with ground-floor retail.

The building’s facade is somewhat unique with dark geometric metal and large panes of glass that allow for ample light
throughout the building. The sponsor also owns and maintains a public park adjacent to the building with a water feature
and a bamboo garden. The park is quite popular with tenants at lunchtime, especially in the warmer months. The lobby
area is modern with high ceilings and features light-colored wood paneling that gives the space a warm feeling without
seeming dated.

Tenant spaces were generally modern, with most of the buildouts being relatively recent. Seyfarth is in the process of
finishing up a renovation, converting some of their more traditional law-firm style office layout into a more modern
configuration. J.P. Morgan’s space was also modern, with typical open-floor-plan desks and executive offices. The space
occupied by J.P. Morgan’s private client group was also well appointed, with marble and mahogany finishes and several
pieces of famous art. Similarly, the Delta Dental, Nuveen, and EY space was recently built out and featured ample light and
open floor plans.

The vacant pre-build space on the second floor is tenant-ready and includes a kitchen area with stainless-steel appliances
and concrete floors, along with several glass partitions to create office or conference room space.

The building also features an underground parking garage with secure bike storage (accessible by key card) and electric-
vehicle charging. Tenants who bike to work can also take advantage of nicely renovated showers and locker rooms, which
are a nice in-building amenity to offer.

Generally, the building is well-maintained and offers its tenants all the modern amenities of most Class A office buildings.
The minimal vacant space, inclusive of the prebuild space, is marketable and there didn’t appear to be any obvious reasons
why the sponsor should have trouble leasing it.
